ARM: arm-soc platform updates for 3.10, part 2

These patches are all for Renesas shmobile, and depend on the earlier
pinctrl updates. Remarkably, this adds support for three new SoCs:
r8a73a4, r8a73a4 and r8a7778. The bulk of the code added for these is
for pinctrl (using the new subsystem) and for clocks (not yet using the
common clock subsystem). The latter will have to get converted in one
of the upcoming releases, but shmobile is not ready for that yet.

The series also contains Renesas shmobile board changes, adding one
board file for each of the three new SoCs.  These boards are using a
mix of classic and device-tree based probing, as there is still a lot of
infrastructure in shmobile that has not been converted to DT yet. Once
those are resolved to the degree that no board specific setup code is
needed, they can get folded into the respective SoC setup files.

From Simon Horman:
Renesas ARM based SoC lager board updates for v3.10

* Use r8a7790 timer setup code to force the
  arch timer to be enabled regardless of the bootloader setting
  - This is necessary for the lager board to boot
