Add support for Atheros AP96 reference board

This is still preliminary and not really tested much. Anyway, this version seems to be enough to get both wired and wireless interfaces working. Buttons and leds are also working. mach-ap96.c is based on mach-wndr3700.c. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> SVN-Revision: 23125
