ARM: dts: Add am335x-boneblack-wireless 

BeagleBone Black Wireless is clone of the BeagleBone Black (BBB) with
the Ethernet replaced by a TI wl1835 wireless module.

This board can be indentified by the BWAx value after A335BNLT (BBB)
in the at24 eeprom:
BWAx [aa 55 33 ee 41 33 33 35  42 4e 4c 54 42 57 41 35  |.U3.A335BNLTBWA5|]
