serial: 8250_pci: add support for MCS9865 / SYBA 6x Serial Port Card

This patch is heavily based on an earlier patch found on the linux-serial
mailing list [1], written by Darius Augulis.

The previous incarnation of this patch only supported a 2x serial port
card.  I have added support for my SYBA 6x serial port card, and tested on
x86.
