ARM: SoC: driver changes

These changes are mostly for ARM specific device drivers that either
don't have an upstream maintainer, or that had the maintainer ask
us to pick up the changes to avoid conflicts. A large chunk of this
are clock drivers (bcm281xx, exynos, versatile, shmobile), aside from
that, reset controllers for STi as well as a large rework of the
Marvell Orion/EBU watchdog driver are notable.

From Tomasz Figa:
This series reworks suspend/resume handling of Samsung clock drivers
to cover more SoC specific aspects that are beyond simple register
save and restore. The goal is to have all the suspend/resume code
that touches the clock controller in single place, which is the clock
driver.
