wl1271: add wl1271 driver files

This driver supports the wl1271 chipset from Texas Instruments based on the
WiLink(tm) 6.0 mobile platform.  Support for wl1273 should be relatively easy
to add.  This chipset is designed for embedded devices, with good powersaving
capabilities.  The wl1271 chipset is the successor of wl1251 and supports the
802.11b/g/n standards, but currently this driver supports only b/g.

More information about this chipset can be found here:
