[PATCH 1/2] serial: 8250_pci: add .probe member to struct pci_serial_quirk

This function, if present, is called early on by the 8250_pci probe; it
can be used to reject devices meant for parport_serial.  (The .init
function cannot be used for this purpose, as it is also called by
parport_serial.)

[PATCH 2/2] parport/serial: add support for Timedia/SUNIX cards to parport_serial

Timedia/SUNIX PCI cards with both serial and parallel ports are
currently supported by 8250_pci and parport_pc individually.  Moving
that support into parport_serial allows using both types of ports at the
same time.

This was successfully tested with a SUNIX 4079T.
