staging: r8712u: Switch driver to use external firmware from linux-firmware

- switch to use LIB80211

- switch to use MAC80211

- checkpatch.pl fixes - only a few remain

- switch from large inline firmware file to use the firmware interface

  and add the file to the linux-firmware package.

Please send any patches to Greg Kroah-Hartman <greg@kroah.com>,

Larry Finger <Larry.Finger@lwfinger.net> and
