[PATCH v2 1/3] ARM: shmobile: marzen: Switch to DT_MACHINE_START

[Simon Horman]

From: Magnus Damm <damm at opensource.se>

Convert the marzen board to use DT_MACHINE_START. With this in
place all mach-shmobile boards use DT_MACHINE_START. Also, this
makes it possible for the r8a7779 SMP code to use DT for CPUs.

So appended DTB is the way forward on this board.

v2 [Simon Horman]
* Select USE_OF in Kconfig
* Provide dt_compat in DT_MACHINE_START
* Provide r8a7779-marzen dts

v1 [Magnus Damm]
