As discussed on the mailing list and voted upon, the coreboot project
is going to move the majority of copyrights out of the headers and into
an AUTHORS file. This will happen a bit at a time, as we'll be unifying
license headers at the same time.
Updated Authors file is in a separate commit.

We keep the support, though. Just now that `libgfxinit` is fixed, we
don't need the distinction anymore. Causally, we also don't need
CPU_INTEL_MODEL_306AX any more.

Beside one tiny fix for framebuffer scaling, this contains a major
refactoring of libgfxinit's configuration infrastructure. With this,
we are finally able to detect CPUs at runtime and only have to confi-
gure a CPU/GPU generation.

Add maximum width and height options and set the default to 2560x1600
(WQXGA). The framebuffer will be scaled up to the displays' native
resolutions. So this should help with tiny fonts on high-DPI displays.
For laptops, reasonable defaults can be set at the mainboard level.

Backlight control of internal panels likely won't work as configuration
for that seems absent in coreboot. Also, libgfxinit doesn't support any
MIPI/DSI connections, yet, and neither Gemini Lake.

linear framebuffer modes. DP display came up.

Its spreading copies got out of sync. And as it is not a standard header
but used in commonlib code, it belongs into commonlib. While we are at
it, always include it via GCC's `-include` switch.
Some Windows and BSD quirk handling went into the util copies. We always
guard from redefinitions now to prevent further issues.

CBLV is not kept up to date by Linux' i915. We should fix that too,
but it will likely take some years until we can always expect it to
work.
For now read the register values directly. To accomodate that we
are not the only one writing those, revise XBQC() to search for
the closest value in BRIG (instead of a lower equal one) and round
more accurately for better matches.

We should always update BCLP, no matter if the driver is ready yet to
process the request. This way it will hold the current value when the
driver initializes.

The _BCM function requires a percentage value. While the
brightness in mailbox3 requires a value in uint8_t. Meaning 255 = 100%.
Previous implementation stored the percentage brightness value resulting
in limiting the brightness to ~40% of it's maximum power.
Only affects brightness control using mailbox3.

In 4a3956d7 (drivers/intel/gma, soc/intel/common: improve
cooperation) the vbt_size parameter was not honored leading to
the use of unitialized variables from the caller. Instead, keep
track of if the vbt is already loaded by using the size returned
from the load. If it's non-zero the vbt has been loaded.

Instead of both featuring their own VBT loaders, use a single one.
It's the compression-enabled one from soc/intel/common, but moved to
drivers/intel/gma.
The rationale (besides making all the Kconfig fluff easier) is that
drivers/intel/gma is used in some capacity on all platforms that load a
VBT, while soc/intel/common's VBT code is for use with FSP.
