ARM: rmobile: Add Beacon EmbeddedWorks RZG2H Dev Kit

The Beacon EmbeddedWorks kit is based on the R8A774E1 SoC also
known as the RZ/G2H.

The kit consists of a SOM + Baseboard and supports microSD,
eMMC, Ethernet, a couple celular radios, two CAN interfaces,
Bluetooth and WiFi.  It shares much of the same design as
the RZ/G2M and RZ/G2N dev kits.
