ath79: add support for Ubiquiti LiteStation SR71

Specifications:

SoC: AR7130
DRAM: 32Mb DDR1
Flash: 16Mb SPI-NOR
LAN: 2x 10/100Mbps via ADM6996 switch on MII
     (1 with PoE)
PCI: 1x mini-PCI
UART: standard UART header
JTAG: yes
LEDs: 8x LEDs

Installation instructions:

The original FIS partitioning does not provide enough
space for the kernel, so the installation must start
with re-partitioning the flash from RedBoot.

The MAC address is stored in the "boardconfig" partition, which is
automatically created.
