Adrian Chadd 7c12b677f5 [ar531x] add initial port for the AR231x/531x series of SoCs. 
These are older MIPS4kc parts from Atheros.  They typically ran at
sub-200MHz and have 11bg, 11a, or 11abg wifi MAC/PHYs integrated.

This port is the initial non-wifi pieces required to bring up the
chip.  I'll commit the redboot and other pieces later, and then
hopefully(!) wifi support will follow.
