PATCH 7/8 ARM: mach-shmobile: r8a7779 and Marzen timer rework

From: Magnus Damm <[email protected]>

Move the SoC specific timer code from Marzen board code to r8a7779 setup code. This makes is possible to share the SoC specific timer code across boards and it also removes the need for a board specific timer structure.
