AA: ar71xx: add support for TP-Link TL-WA7510N

Backport of r34187.

It is mostly the same as TL-WA901N. WLAN and LAN
are working. LAN LED is working. WLAN signal
strength LEDs are not working yet.

[juhosg:
  - cleanup commit message
  - move non kernel related stuff into separate changes
  - rename and refresh 615-MIPS-ath79-TL-WA7510N-v1-support patch
  - merge WA7510N support into the mach-tl-wa901nd.c file
  - add 3.6 support]
