Hi,

I don't think this is needed as piix will continue to be the default.
It will also cause trouble with libvirt when pc-q35-experimental goes
away some day.

When we allocate a reserved_va for the guest, the kernel will likely
choose an address well above 4G. At which point we must use a pair
of movabsq+addq to form the host address. If we have OS support,
set up a segment register to point to guest_base instead.

OpenBIOS on sparc64 only support Standard VGA and not Cirrus VGA. Don't
build Cirrus VGA support so that it can't be selected.
This fixes the breakage introduced by commit f2898771.
