soc/braswell: ensure ACPI opregion restored on S3 with GOP init

The Intel GMA ACPI opregion address needs to be set on S3 resume,
otherwise the Windows display driver fails to re-initialize correctly.
Fix by ensuring the address is set correctly regardless of display
init type used (GOP or VBIOS).

Test: build/boot on google/edgar, ensure internal display functional
following S3 resume under Windows 10.
