Log Message:
radeon: fix and enable ACPI methods for getting ROM BIOS

The hacky way of getting the BIOS mapped only works on x86. ACPI
should be preferred if available. Makes BIOS reading though VFCT
work on aarch64 with EDK2. (But only if EDK2 has POSTed the GPU.)

XXX amdgpu should get the same treatment.
