Move brcm80211 to mainline

With the latest series of cleanup patches merged in by Greg KH, I'd like to
once again propose moving brcm80211 out of staging and into mainline.

I've put together a patch to add a copy of the current sources from
staging-next into wireless-testing:drivers/net/wireless/brcm80211.

The patch is somewhat large, so I've posted the patch at:

http://linuxwireless.org/en/users/Drivers/brcm80211?actio...

Changes from the previous version:

V2:
- Resolve checkpatch issues
- Fix issues on big-endian platforms (MIPS BE, PPC, and SPARC)
- Cleanup architecture-specific code
- Fix power save, locking, and scan issues in brcmfmac
- Elimimnate 'void *' casts in brcmsmac
- Fix entry for brcm80211 drivers in drivers/net/wireless/Kconfig
- Use cordic and crc8 kernel library functions
- General code cleanup, restructuring, and dead code removal

The only difference between these sources and the ones in staging-next are:
	- necessary Kconfig and Makefile adjustments for the new driver location
	- one cleanup of a checkpatch warning (as indicated below)

The brcmsmac driver has been verified to work on x86 (both 32- and 64-bit), PPC
(64-bit), SPARC, MIPS BE, and ARM.  The brcmfmac driver has been verified to
work on x86 32-bit and ARM (additional testing is in progress, but getting a
working sdio controller on some of the other platforms has been challenging).

The drivers compile cleanly for x86 (32- and 64-bit), PPC (32- and 64-bit),
SPAR, MIPS BE, MIPS LE, and ARM.

Thanks,
