Add in the AP93 configuration file.

The AP93 has:

* AR7240 - mips24k processor with integrated 10/100 switch and
  various other peripherals;
* AR9283 - 2x2 2.4GHz 802.11n (with calibration data in flash);
* 64MB RAM;
* 16MB SPI flash.

The switch code detects as an AR8216 at the present moment, which isn't
_entirely_ strictly true.  However, the MII/MDIO routing in AP93.hints
works - the arge0 MAC connects to PHY4 in the switch, but via the
switch internal MDIO bus.  The switch connects to arge0's MDIO bus,
but only to export the switch registers.

Thanks to stb and ray for the switch work, and ray for helping determine
what the correct switch hints should be for this thing.
