ARM: meson: Add Khadas VIM2 board support
This adds platform code for the Khadas VIM2 board based on a
Meson GXM (S912) SoC with the Meson GXM configuration.
This initial submission supports UART, MMC/SDCard and Ethernet.
USB is partially supported.
All the code is from Neil Armstrong! I just rebased the code, do
some cleanup and tested on my board.
