Merge branch 'clockevents/cmt-mtu2-tmu-cleanups' into clockevents/3.16

This patch set cleans up the Renesas CMT and TMU drivers in preparation for DT
support.

The first 35 patches are a bunch of necessary cleanups that reorganize the CMT
and TMU drivers, their platform data, and the memory, interrupt and clock
resources they expect. As a result the drivers accept a new platform data
model close to the hardware with supports for all the timer channels using a
single device.

The next 13 patches (36/52 to 48/52) move all CMT and TMU platforms from the
old to the new platform data model. Patches 49/52 to 52/52 then drop support
for the old model and perform one more cleanup.
