Arthur Heymans 944eefc886 UPSTREAM: x4x/gma.c: Add VESA native resolution mode
This patch implements native resolution, VESA mode, on the VGA output of
x4x.

It relies on EDID to modeset, but has a fallback-mode (640 x 480 @
60Hz) if this is no EDID could be found. This fallback mode only works
in textmode since in VESA mode some payloads (grub2) rely on VBE info,
which is being generated from an EDID.

BUG=None
