Add code to setup the r8a7791 PFC for the Koelsch board.
At this point serial consoles are added, and in the near
future other platform-device-only devices will be added
here like for instance the r8a7791 DU.

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)

In R-Car GPIO hardware block, 'chattering removal' feature can be
enabled on GPIO-n-[3:0] pins, but it's not supported on rest of pins
GPIO-n-[31:4].
Set an appropriate debounce interval, instead. We could confirm that
spurious/unnecessary GPIO interrupts are prevented by this settings.
Based on work for the lager board by Shinya Kuribayashi.
