Fix up more strange byte writes to the PCI_ROM_ADDRESS config word
It's a dword thing, and the value we write is a dword. Doing a byte
write to it is nonsensical, and writes only the low byte, which only
contains the enable bit. So we enable a nonsensical address (usually
zero), which causes the controller no end of problems.
Trivial fix, but nasty to find.
