PATCH 3/7 ARM: mach-shmobile: r8a7779 and Marzen base support

From: Magnus Damm <[email protected]>

Initial prototype support for the r8a7779 SoC and the Marzen board.

Only SCIF ports and the TMU are supported at this point.

To keep things simple only entity-mapped virt-to-phys mappings are supported. This forces drivers and other SoC glue code to make use of ioremap(). We cannot support early serial console due to virtual address space collisions with the ARM kernel.
