xen_pt: Fix passthrough of device with ROM.
QEMU does not need and should not allocate memory for the ROM of a
passthrough PCI device. So this patch initialize the particular region
like any other PCI BAR of a passthrough device.
When a guest will access the ROM, Xen will take care of the IO, QEMU
will not be involved in it.
Xen set a limit of memory available for each guest, allocating memory
for a ROM can hit this limit.
