Bring in Andrew Thompson's port of Sepherosa Ziehau's bwi driver for

Broadcom BCM43xx chipsets.  This driver uses the v3 firmware that
needs to be fetched separately.  A port will be committed to create
the bwi firmware module.

The driver matches the following chips: Broadcom BCM4301, BCM4307,
BCM4306, BCM4309, BCM4311, BCM4312, BCM4318, BCM4319

The driver works for 802.11b and 802.11g.

Limitations:
	This doesn't support the 802.11a or 802.11n portion of radios.
	Some BCM4306 and BCM4309 cards don't work with Channel 1, 2 or 3.
	Documenation for this firmware is reverse engineered from
		 http://bcm.sipsolutions.net/
	V4 of the firmware is needed for 11a or 11n support
		 http://bcm-v4.sipsolutions.net/
	Firmware needs to be fetched from a third party, port to be committed

# I've tested this with a BCM4319 mini-pci and a BCM4318 CardBus card, and
# not connected it to the build until the firmware port is committed.
