ar71xx: add kernel support for TPLINK WR720N v3
Add support for TPLINK WR720N v3 which has 4MB flash, 32MB ram, 2 ethernet interfaces, 1 USB 2.0 port. The patch is mostly a modification from mach-tl-wr703n.c. GPIO numbers for the slider switch is from mach-tl-mr3020n.c. Tested on my device and they worked fine.
