The original ME code was assuming that the only type of messages
it would send were MKHI type and so it had some embedded checks
for that header and that type of message.
In order to support ICC messages this needs to change to handle
different header types, so now the header will be sent first
and then the data will follow, rather than the two both being
sent in the same low-level function.
This change has no real affect on the system, subsequent commit
will add new ICC messages.

The end of the _PS0 method that is supposed to transition the
XHCI device to D0 state is instead putting it in D3 state.
This triggers a PME_B0 GPE which causes a Notify to the XHCI
ACPI Device in the kernel and that increments the wakeup counter
and causes aborted suspends.
Instead if we just leave the device in D0 where it should be
after executing this function then the PME_B0 is not generated
and the kernel does not see a wakeup on XHCI.
Similarly I changed the _PS3 method to always put the device in
D3 at the end of the method, rather than depending on the state
to be D3 at the start.
BUG=chrome-os-partner:21663

Before this change the kernel would see the following sequence
when trying to suspend when the XHCI controller is in D3cold:
kernel: ACPI: Execute Method [\_SB_.PCI0.XHCI._PS0] (Node ffff88017802bf28)
kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [XHCI] (Device) Value 0x02 (Device Wake) Node ffff88017802bc30

kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [HDEF] (Device) Value 0x02 (Device Wake) Node ffff88017802b1b8
kernel: xhci_hcd 0000:00:14.0: power state changed by ACPI to D0

kernel: xhci_hcd 0000:00:14.0: enabling bus mastering

kernel: PM: Wakeup pending, aborting suspend
kernel: last active wakeup source: 0000:00:14.0
Now it does not get a notification (due to PME_B0) when going to D0
on the way into suspend. XHCI goes from D3cold to D0 (in order to
be able to read mmio) and then back to D3hot before suspend.

The existing GPIO config routines for SDMMC0-2 are over-generalized
and somewhat confusing as a result. It would work nicely if all SDMMC
ports were configured in the same fashion, but there are a few
exceptions.
For example, the inner function runs differently if we're using 8 bits
of data instead of 4, so a big chunk is skipped for SDMMC2. SDMMC0
requires SD_0_CDn to be an output rather than alternate function and
must have a value set.
This patch trades some verbosity for simplicy. Now the SDMMC GPIO
configuration a straight-forward sequence of GPIO operations
without any exceptions.

which is changed and improved. We took the chance to remove un-needed
files, and also to remove some foolish u-boot habits, but not all of
them. That will take time.
With these changes we get graphics.
Since the only mainboards we have with 16 bit graphics are 5:6:5,
adjust edid.c to just use that format. If at some future time we need
4:4:4, which seems unlikely, we'll need to add a function to adjust
the lb_framebuffer. Note that you can't just divine this from the EDID,
as the graphics pipe format need not match the actual final format used.
The EDID reading works. We've been requested to support hard-coded
EDIDs and that will come in the next revision. Currently the hard-coded
EDID is ignored for testing.

In a previous commit the contents of wakeup_need_reset were removed because
the GPIO it referred to wasn't connected to anything on pit. I didn't realize
at that time that that could have been because we hadn't tried getting
suspend/resume working on pit and hadn't updated that file. On snow, the GPIO
is the recovery mode pin. This change updates pit to have the right GPIO,
kirby to read that GPIO, and makes the comments for both pit and kirby more
explicit and spells out the fact that this is the recovery mode GPIO.
Having a check here at all may still be a holdover from snow that isn't
applicable to pit or kirby, but since there is a parallel as far as the
recovery mode GPIO we might as well make them match while waiting for more
information.

Like on kirby, this header had a single constant in it that was actually used.
This change moves that constant inline and gets rid of the header file.

A previous change removed init_timer from timer_monotonic_get because its old
implementation set up the PWM based timer which was going away. It would still
be a good idea to initialize the timer at that point, just not the pwm.

The timer code was supposed to be using the mct, and also using the monotonic
timer infrastructure instead of the get_timer function. This change had been
made for the 5250 but not yet for the 5420.

When the const was removed from write function arguments, a related bug in the
5250 code was fixed so that it would still compile. Unfortunately, that same
change needed to be made to the 5420.

When the EC requests the host to throttle (for charging or thermal
related reasons) the package power consumption will be limited.
Right now this is set at 12W but that is somewhat arbitrary and may
need tuning.
1) define the THRT method in \_TZ scope for EC to call
2) enable SCI events for throttle start and stop
3) define the power limit at 12W and set it in NVS

Two new events possible from the EC for starting and stopping throttle.
These are handled in a per-board method that is defined under the
thermal zone. This is not quite where I wanted it but the scoping
rules in ACPI don't let me have a defined external object in the
same scope.

1. Kirby doesn't have a backlight enable GPIO on the AP since that's handled
entirely by the DP-to-LVDS bridge.
2. There is no tps65090 on the other side of the EC who's settings need to be
adjusted. If we need to turn on the LCD or backlight power manually, it will
have to be done in a different way.
3. The PMIC doesn't provide a 32KHz output for the audio codec.

The function in wakeup.c isn't applicable on kirby. The only constant in
exynos5420.h that was used was the speed of the 4th i2c bus. Instead of having
a whole header file for that one constant used in one place, the constant is
just moved inline along with the comment it had in the header.
