[PATCH] shpchp: Use dword accessors for PCI_ROM_ADDRESS 

PCI_ROM_ADDRESS is a 32 bit register and as such should be accessed using
pci_bus_{read,write}_config_dword().  A recent audit of drivers/ turned up
several cases of byte- and word-sized accesses.  The harmful ones were fixed
by Linus directly.  This patches up one of the remaining
harmless-but-still-wrong cases caught in the dragnet.
