Reset BARs and a couple of other registers on bus reset, as per PCI spec.
This commit breaks Windows XP restart. After a restart Windows switches from 800x600 cirrus logic vga to 640x480 standard vga.
Reposting fom qemu tree now.
So I just sent patches for pcbios and seabios to fix this. Once applied, reset works fine. Further, we can also fix PCI incompliancy in cirrus, disabling memory and i/o on reset.
To apply these patches:
- apply pcbios and seabios patches
- generate binaries and commit
- apply this patchset

qemu: update seabios to enable i/o for cirrus
