isapc: Fix non-KVM qemu boot (read/write memory for isapc BIOS)
The isapc machine with seabios currently requires the BIOS region
to be read/write memory rather than read-only memory.
KVM currently cannot support the BIOS as a ROM region, but qemu
in non-KVM mode can. Based on this, isapc machine currently only
works with KVM.
To work-around this isapc issue, this change avoids marking the
BIOS as readonly for isapc.
This change also will allow KVM to start supporting ROM mode
via KVM_CAP_READONLY_MEM.
