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.
