Now that r7s72100 has CCF support, remove the legacy Genmai reference
Kconfig bits for the non-multiplatform case.

Starting from this commit Genmai board support is always enabled via
CONFIG_MACH_GENMAI, and CONFIG_ARCH_MULTIPLATFORM is used to select
between board-genmai.c and board-genmai-reference.c

The file board-genmai-reference.c can no longer be used together with
the legacy sh-clk clock framework, instead CCF is used.

Introduce a new clock workaround function used by DT reference
code on the mach-shmobile subarchitecture. The new function
shmobile_clk_workaround() is used to configure clkdev to
allow DT and platform devices to coexist. It is possible for
the DT reference board code to also request enabling of the clock
in case the driver does not implement clock control.

Add Koelsch and r8a7791 to CONFIG_SHMOBILE_MULTI. At this
point CCF is not yet supported so you cannot run this code
yet. For CCF support to happen several different components
are needed, and this is one simple portion that moves us
forward. Other patches need to build on top of this one.

Koelsch board support exists in 3 flavors:
1) SHMOBILE_MULTI, MACH_KOELSCH - board-koelsch-reference.c (CCF + DT)
2) SHMOBILE, MACH_KOELSCH_REFERENCE - board-koelsch-reference.c (DT)
3) SHMOBILE, MACH_KOELSCH - board-koelsch.c (legacy C code)

When CCF is done then 2) will be removed. When 1) includes same features
as 3) then 3) will be removed.
