x86/acpi: Use initialized VBIOS in VFCT table
AMD VBIOS option ROMs often modify themselves during initialization. Check for the presence of a VBIOS at 0xc0000 before populating the VFCT table. If a matching ROM is found, use it for the source of the copy. Tested on Gardenia (Stoney) variant by observing amdgpu driver's dmesg output.
