tegra124: Add a test function which spams exclamation points on the UART.
This function spews characters on the console and, until we have a working
console, is an easy way to see whether the system boots to a particular point.
For some reason waiting for transmitter to be empty hangs, but transmitting
characters still works.

tegra124: Re-enable waiting for the transmitter to empty in the test function.
The compiler was emitting code compatible with armv7-a, but the bootblock was
running on a core which uses armv4t. By coincidence, it was emitting an
instruction which is unavailable on armv4t when checking the value of the
UART's LSR register. Now that the bootblock is compiled with more appropriate
flags, this code can be re-introduced.

tegra124: Seperate out the non-UART specific hardcoded init in the bootblock.
The hardcoded init in the test function in the bootblock is actually useful
generally because it doesn't belong in the UART driver itself but is necessary
for the UART to work. Until we have real implementations for the pinmux, etc.,
we can use that code to get the UART and console going.

tegra124: Implement and enable serial console support for tegra124.
The driver is very similar to the 8250 driver, except it isn't in two parts,
and it also spaces its registers 4 bytes apart instead of having them directly
adjacent to each other.
Also, eliminate the UART test function in the bootblock. It's no longer needed
since the actual console output serves the same purpose.
Right now the clock divisor is fixed for now, and we'll want to actually
figure out what value to use at some point.

Peppy had some issues with FUI. We decided it was time to create
peppy-specific gma.c and i915io.c files. Using yabel and the i915tool,
we generated a replay attack, then interpolated against the slippy
i915io.c to get something working.
Also, in preparation for moving code out of the mainboard gma.c to
generic driver code, we got rid of some hardcodes in the mainboard
gma.c that have no business being there. The worst were the
computation of gmch_[m,n] and it turns out that we had some
long-standing bugs related to confusion about 'bpp'. I've killed the
word bpp everywhere I could because there are at least 3 things that
correspond to bpp. We now have framebuffer, pipe, and panel bpp. The
names are long because I want to avoid all the mistakes we've all been
making in the last year :-) Sadly, that means a lot of changes not just
peppy-related, but they are simple and in a good cause.
The test pattern generation is driven by a global variable in
mainboard/peppy/gma.c. I've found in the past that it's very useful
to have a function like this available, as one can activate it while
using a jtag debugger: halt at the right place in ramstage, set the
variable to 1, continue. It's not enough code to worry about always
including.
The last hard-codes for M and N registers are gone, and the function
to set from generic intel_dp.c code works. To avoid screen trash on a
dev mode boot, which we liked but nobody else did :-), we now take the
time to put a pleasing background color that sort of doubles as a
power LED.
Rough timing is ramstage start is at 2.2, and dev setup is done at
3.3. These new platforms are depressingly slow to boot. Rom init alone
is taking 1.9 seconds. 13 years ago it was 3 seconds from power on to bash
prompt. These CPUs are at least 10x faster and take much longer to get going.
Future work, once we get this through, is to move more functions to the
intel driver, and combine the mainboard i915io.c into the mainboard gma.c.
That separation only existed because i915io.c was generated by a tool, and it
had lots of ugliness. Most ugliness is gone.

Since commit 17fec8a0 [1]
drm/i915: Use Graphics Base of Stolen Memory on all gen3+
present in the Linux kernel since version 3.12, 3D does not work
anymore [2].
Comparing the graphics registers, in this case that means output of
`intel_reg_dumper`, the vendor Video BIOS is setting the register
PGTBL_CTL/PGETBL_CTL, only documented in the i965 datasheet [3], to
`0x3ffc0001` on a system with 1 GB of RAM, while native graphics init
sets it to `0x3f800001`.
Currently native graphis init sets the GTT right above the base
address of stolen memory. The Video BIOS sets it below the top of
memory. The Linux Intel driver expects it to be below top of memory, so
do it this way, by setting the address to TOM minus the size of the GTT,
which is hardcoded to 256 KiB.
As `PGETBL_CTL` is zero by default, reading its value in the beginning
is not necessary and is only confusing. Make it clear that the code
calculates the value.
There is still a PTE error reported during boot, but 3D works
with Linux 3.12+ and no user visible problems are shown.
