vgabios: PMM scan was incorrectly depending on a zero %ds segment.
Make sure the PMM scanning code uses the GET_FARVAR macro. (The
existing code only worked because SeaBIOS happens to call the vgabios
in bigreal mode with %ds == %ss = 0.) Also, the scan doesn't require
bigreal mode - use accesses relative to the SEG_BIOS segment so that
the scan can work in regular real mode.
