board: microsoft: surface-rt: add Microsoft Surface RT support

Surface RT is a hybrid tablet computer developed and manufactured
by Microsoft and shipped with Windows RT. The tablet uses a 1.3 GHz
quad-core Nvidia Tegra 3 chipset with 2 GB of RAM, features 10.8
inch 1366x768 screen and 32/64 GB of internal memory that can be
supplemented with a microSDXC card giving up to 200 GB of
additional storage.
