Bruce M Simpson fb1d9b7f41 Allow uart(4) to use MSI interrupts on single-port PCI instances. ...

Do this here as puc(4) disallows single-port instances; at least
one multi-port PCIe UART chip (in this case, the ASIX MCS9922)
present separate PCI configuration space (functions) for each UART.

Tested using lrzsz and a null-modem cable. The ExpressCard/34
variants containing the MCS9922 should also use MSI with this change.
