[patch 3/3] 8250_pci: add support for netmos 9835

[akpm@linux-foundation.org]

From: 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.
