ARM: mach-shmobile: r8a7779, marzen: Reference DT implementation

[Simon Horman]

Provide minimal DT initialisation for the r8a7779 SoC and
marzen board as a reference for developers.

In general the idea is to grow the hardware supported by this
initialisation as DT coverage of relevant drivers and other code
grows.
