PATCH: serial port configuration problem

[David Hinds]

This fixes a problem with certain GSM/GPRS cards that have odd CIS
information (config entries that disagree about how many IO ports are
needed, which confuses the heuristics in serial_cs for guessing the
correct number of UARTs).

This is already in pcmcia-cs and in the 2.4 serial_cs but somehow has
not made it into 2.6.
