device/pci_rom: Fix on-board optionrom address
The function pci_rom_probe() may be called multiple times
for a device. For cases where CBFS does not contain optionrom
file, only the first time probing for the on-board ROM
chip worked.
PCI_ROM_ADDRESS_ENABLE is set on the first run. Mask out all
the reserved bits of PCI_ROM_ADDRESS register to get correct
physical address for rom_header.
