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.
