board: xiaomi: mocha: add Xiaomi Mi Pad A0101 support
The Mi Pad is a tablet computer based on Nvidia Tegra K1 SoC which
originally ran the Android operating system. The Mi Pad has a 7.9" IPS
display with 1536 x 2048 (324 ppi) resolution. 2 GB of RAM and 16/64 GB of
internal memory that can be supplemented with a microSDXC card giving up to
128 GB of additional storage.
