[PATCH] USB: add Option Card driver

This patch adds a new driver for "Option" cards.  This is a GSM data card,
controlled by three "serial ports" which are connected via an OHCI adapter,
all located on an oversized PC-Card.  It's sold by several GSM service
providers.

Traditionally, this card has been accessed via the standard serial driver
and appropriate vendor= and product= options.  However, testing has
revealed several problems with this approach, including hung data transfers
and lost data blocks when receiving.

Therefore, I've written a separate driver.
