Buffalo Airstation build support

Implement support for Buffalo, "OpenWRT Friendly" Atheros Mips 24k board
in the wifi builder.

I'm still working on the kernconf, but the wifi builder support will
create and image called /tftpboot/wzr300hp-tftp.bin that is accepted by
the router when pushed in via tftp and uboot following the instructions
at:
http://wiki.openwrt.org/toh/buffalo/wzr-hp-g300h#oem.installation.using.the.tftp.method

The kernel panics right now, and I'll follow up with a kernconf/hints
patch for review once I have fixed my initial crash and burn.BUFFALO
