The hack seems to set up coreboot display to use window B. We eventually
want to use the same window as the kernel is going to use (I think), so
that's what this patch does.
We think window B is hiding the contents of window A, which is why we
weren't seeing ChromeOS UI come up. This fix makes that not happen anymore
by making coreboot use window A.

This improves boot time in 2 ways for a firmware upgrade:
1. Normally MRC would detect the S0 state without an MRC cache
even though it's told to the S5 path. When it observes this
state a cold reset occurs. The cold reset stays in S5 for
at least 4 seconds which is time observed by the end user.
2. As the EC was running RW code before the reset after firmware
upgrade it will still be running the older RW code. Vboot will
then reboot the EC and the whole system to put the EC into RO
mode so it can handle the RW update.
The issues are mitigated by detecting the system is in S0 with
no MRC cache and the EC isn't in RO mode. Therefore we can do the
reboot without waiting the 4 secs and the EC is running RO so
the 2nd reboot is not necessary.

Added a method in each temp sensor to disable the aux trip points
and then a wrapper function to call this method for each enabled
temperature sensor.
The event handler function is changed to not use a switch statement
so it does not need to be serialized. This was causing issues
with nested locking between the global lock and the EC PATM mutex.
Some unused code in temp sensors that was added earlier is removed
and instead a critical threshold is specified in _CRT.
The top level DPTF device _OSC method is expanded to check for the
passive policy UUID and initialize thermal devices. This is done
for both enable and disable steps to ensure that the EC thermal
thresholds are reset in both cases.
Additionally the priority based _TRT is specified with TRTR=1.

This adds the option to put LPSS and SCC devices into ACPI mode
by saving their BAR0 and BAR1 base addresses in a new device
NVS structure that is placed at offset 0x1000 within the global
NVS table.
The Chrome NVS strcture is padded out to 0xf00 bytes so there
is a clean offset to work with as it will need to be used by
depthcharge to know what addresses devices live at.
A few ACPI Mode IRQs are fixed up, DMA1 and DMA2 are swapped and
the EMMC 4.5 IRQ is changed to 44.
New ACPI code is provided to instantiate the LPSS and SCC devices
with the magic HID values from Intel so the kernel drivers can
locate and use them.
The default is still for devices to be in PCI mode so this does
not have any real effect without it being enabled in the mainboard
devicetree.
Note: this needs the updated IASL compiler which is in the CQ now

Install the BL1 and set up the checksum in the Makefile instead of relying on
post processing. Import the exynos checksum script, split it in two and
simplify it significantly. Stop putting the CBFS header in the midst of the
bootblock so that it can be checksummed before CBFS is put together. Stop
saving space for it and leaving an anchor in the bootblock which nobody looks
for.
