drivers/intel/gma: Move IGD OpRegion to CBMEM 

It never was in GNVS, it never belonged among the ACPI tables. Having
it in CBMEM, makes it easy to look the location up on resume, and saves
us additional boilerplate.

TEST=Booted Linux on Lenovo/X201s, confirmed ASLS is set and
     intel_backlight + acpi_video synchronize, both before and
     after suspend.
