Based on original ar71xx eg200 board files
Tested working:
* usb hub, storage and serial port
* ethernet
* wifi
* leds
* button
sysupgrade from self->self passes validity checks.
sysupgrade from old ar71xx->ath79 passes. (however this doesn't migrate
wireless driver configs)
Only unknown issue is the existance of a /sys/class/leds/ath9k-phy0,
which doesn't "exist"
