Enable build of EMEV2 and KZM9D DT Reference in
case of ARCH_MULTIPLATFORM and ARCH_SHMOBILE_MULTI.

IS_ENABLED() is leaves the clock-emev2.c file out

Add ARCH_SHMOBILE_MULTI to mach-shmobile that can be used
to enable ARCH_MULTIPLATFORM on selected SoCs and boards.

The headers stay under arch/arm/mach-shmobile/include/mach/
for now, they can and will be migrated independently over time.

Move shared clock.c file and per-SoC clock-xxx.c files

The regular ARCH_SHMOBILE case with legacy SH clock framework
will build just as before with this patch applied, however
the case when COMMON_CLK=y will exclude all the clock files.

Add a DT reference implementation for the KZM9D board.

Only DT devices are used in this case. UART, STI, GPIO

There is still a board specific C file used for enabling
legacy SH clocks. This file will be removed after we have
moved over to common clocks.

Update the EMEV2 struct map_desc to exclude the SMU
and also include the ->map_io() callback in the DT
version of EMEV2 board support.

The EMEV2 SMP code can these days perform ioremap()
early on without the SMU information in the io_desc[].

To correctly support SMP in case of DT-only board
support then the ->map_io() callback is needed.
