ramips: Support for RAMIPS based Tripmate HT-TM02 board

Provides support for the Tripmate HT-TM02 personal router including LEDs and
reset button. “Mode” switch is not supported. New profile includes full set
of packages required to enable LEDs, USB, and LUCI. Patches were applied
against trunk snapshot r42649. Functionality has been tested in AP, basic wifi
client, wifi router, and routed client modes - all good.
