The bulk of this branch is updates for Renesas Shmobile. They are still
doing some enablement for classic boards first, and then come up with DT
bindings when they've had a chance to learn more about the hardware. Not
necessarily a bad way to go about it, and they're looking at moving some
of the temporary board code resulting from it to drivers/staging instead
to avoid the churn here.
As a result of the shmobile clock cleanups, we end up merging quite a
bit of SH code here as well. We ended up merging it here instead of in
the cleanup branch due to the other board changes depending on it.

SCIF0 and SCIF1 are used as debug serial ports. Enable them and
configure pinmuxing appropriately. We can now remove the clkdev
registration hack for SCIF devices from the Koelsch reference board
file.

The SCIF driver is transitioning to platform resources. Board code will
thus need to define an array of resources for each SCIF device. This is
incompatible with the macro-based SCIF platform data definition as an
array. Rework the macro to define platform data as individual
structures.
