Netgear WNR612 v2:
- cpu Atheros AR7240 (Python) @400MHz
- flash 4MB
- ram 32MB
- ethernet 10/100: 1xwan + 2xlan (only two)
- radio AR9285
As there is a rebranded WNR612v2 called ON Networks N150R, add
a dtsi which includes all device support, and add a separate dts
for the device only (with a separate one for the subsequent N150R).
