soc/intel/baytrail: add support for Intel GMA OpRegion
Add global/ACPI nvs variables required for IGD OpRegion.
Add functions necessary to generate ACPI OpRegion, save the
table address in ASLB, and restore table address upon S3 resume.
Implementation largely based on existing Broadwell code.
Test: boot Windows 10 on google/squawks with Tianocore payload and
GOP display init, observe display driver loaded and functional,
display not black screen when resuming from S3 suspend.
