[PATCH 2/2 #2] 8250_pci: add support for netmos 9835

[Jiri Slaby <jirislaby@gmail.com>]

Most of netmos 9835 hardware is handled by parport-serial.
IBM introduces a device which doesn't have any parallel ports and
have screwed subdevice PCI id (not corresponding to port numbers).

Handle this device (9710:9835 1014:0299) properly.
