Let the multiplatform Koelsch support boot with the legacy DTS for
Koelsch as well as the Koelsch reference DTS.

Now that the common clock framework is supported, the clock lookup
entries in clock-r8a7791.c are not registered anymore. Devices must
instead reference their clocks in the device tree. However, SCIF and CMT
devices are still instantiated through platform code, and thus need a
clock lookup entry.
Retrieve the SCIF and CMT clock entries by name and register clkdevs for
the corresponding devices. This will be removed when the SCIF and CMT
devices will be instantiated from the device tree.

The common clock framework is initialized in the rcar_gen2_init_timer()
function, remove the of_clk_init() call.

Hook in shmobile_init_late() on Koelsch. This enables some PM
related things like CPUIdle and Suspend-to-RAM.
With this patch applied it is possible to use Suspend-to-RAM:
# echo enabled > /sys/class/tty/ttySC6/power/wakeup
# echo mem > /sys/power/state
(wake by sending a character on the serial console)

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.

Add DT reference support for the r8a7791 Koelsch board.
This board support file will be used together with common
clocks and multiplatform in the future.
