staging: brcm80211: add fullmac driver

This patch to the existing bcm80211 directory in the staging tree adds fullmac
driver support for the BCM4329 SDIO chip from Broadcom.  Configuration of the
mac80211 driver or the fullmac driver can be done through menuconfig.

+Broadcom fullmac driver
+
+This is production driver.
+
+What's here
+===========
+- Completely open source host driver, no binary object files
+- Features Broadcom's OneDriver architecture (single source base for
+  supported chips and architectures)
+- On-chip firmware loaded using standard request_firmware()
+- Support for BCM4329(SDIO)
+
+What's done
+==========
+- Integration with cfg80211 stack
+- Most of Mac functionality is performed in dongle
+- A-MPDU single stream rates
+- BCM4329:	Dualband, Single stream, 20MHz channels
+
+Firmware installation
+======================
+Firmware is available from the Linux firmware repository at:
+
+	git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git
+	http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git
+	https://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git
+
+For 4329 chip, copy brcm/bcm4329-fullmac-4-218-248-5.bin and
+bcm4329-fullmac-4-218-248-5.txt to /lib/firmware/brcm
