nb/intel/*/gma: Port ACPI opregion to older platforms

Port the ACPI opregion implementation that resides in
drivers/intel/gma to older platforms.

It allows to include a vbt.bin and allows GNU/Linux to load the
opregion as ASLS is being set.

Windows' Intel will likely ignore it as it relies on legacy VBIOS
to be loaded at 0xc0000.

Tested successfully on DG43GT (x4x) with vbt.bin,
with X200 (gm45) with vendor option rom and
D945GCLF (i945) with fake vbt.
