drv/intel/gma/opregion: Add common init_idg_opregion()
Add a new common method to initialize ACPI OpRegion.
* Try to locate vbt.bin in CBFS.
* Try to locate VBIOS in CBFS.
* Keep existing code to probe at 0xc0000.
Tested on Lenovo T430 (sandybridge) using vbt.bin, tested using buggy
VBIOS with wrong vbt_offset, tested with fake vbt written by NGI at
0xc0000.
Tested with https://review.coreboot.org/#/c/21766/ on i945 (using fake
vbt at 0xc0000), x4x (using vbt.bin) and gm45 (using vendor VBIOS).
In all cases linux was successfully provided with VBT from ACPI
opregion.
