ARM: SoC: driver changes

Browse source 
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.
