A global flag oprom_is_loaded was used to indicate to
U-boot that VGA option ROM was loaded and run, or that
native VGA init was completed on GMA device.
Implement this feature without dependency to CHROMEOS option
and replace use of global variable oprom_is_loaded with call
to gfx_get_init_done().

The new edid functions support converting the edid to an lb_framebuffer.
Use them. Also, since panels seem to set bits per color instead of bits
per pixel, just force the right value in the edid struct.
Add helpful comment because people don't always believe we need to set
the pallette.
While we're at it, fix a problem that caused it to not compile.

coreboot tables are, unlike general system tables, a platform
independent concept. Hence, use the same code for coreboot table
generation on all platforms. lib/coreboot_tables.c is based
on the x86 version of the file, because some important fixes
were missed on the ARMv7 version lately.

This code is taken from an EDID reader written at Red Hat.
The key function is
int decode_edid(unsigned char *edid, int size, struct edid *out)
Which takes a pointer to an EDID blob, and a size, and decodes it into
a machine-independent format in out, which may be used for driving
chipsets. The EDID blob might come for IO, or a compiled-in EDID
BLOB, or CBFS.
Also included are the changes needed to use the EDID code on Link.

This is a new state machine. It is more programmatic, in the
case of auxio, and has much more symbolic naming, and very few
"magic" numbers, except in the case of undocumented settings.
As before, the 'pre-computed' IO ops are encoded in the iodefs
table. A function, run, is passed and index into the table and
runs the ops.
A new operator, I, has been added. When the I operator is hit,
run() returns the index of the next operator in the table.
The i915lightup function runs the table. All the AUX channel ops
have been removed from the table, however, and are now called as
functions, using the previously committed auxio function.
The iodefs table has been grouped into blocks of ops, which end in
an I operator. As the lightup function progresses through startup,
and the run() returns, the lightup function performs aux channel
operations.
This code is symbolic enough, I hope, that it will make haswell
graphics bringup simpler.
i915io.c, and the core of the code in i915lightup.c, were
programatically generated, starting with IO logs from the DRM
startup code in the kernel. It is possible to apply the tools that
do this generation to newer IO logs from the kernel.

Add a new operator, P, for the state machine, meaning
implement a palette fill.
Implement a function (palette) that fills the palette when the
P operator is hit.
This replaces 256 lines in the state machine table with 1.

For full integration of FUI into coreboot, we need aux channel
communcations. The intel_dp.c is a file taken from Linux and is
used for aux channel comms. This file has been cut down to work
with coreboot. For now it is associated with the link mainboard
until we get a better handle on how this all fits together. This
code is almost certainly usable on other platforms in the long term.
But one step at a time.
