[PATCH v2 1/2] ARM: shmobile: r8a7790: Initialise clocks and SCIF in r8a7790_add_dt_devices()

This is sufficient to allow boot of the Lager board with
a console without boards-lager.c compiled into the kernel.
This is an example of a minimal but still useful initialisation
of the board using DT as much as possible.
Also provide r8a7790_add_dt_device() in
r8a7790.h to allow it be used from a boards-lager-reference.c
file which will be added by a subsequent patch.
