ARM: SoC driver updates for v4.1

Browse source 
Driver updates for v4.1. Some of these are for drivers/soc, where we find more
 and more SoC-specific drivers these days. Some are for other driver subsystems
 where we have received acks from the appropriate maintainers.
 
 The larger parts of this branch are:
 
 - MediaTek support for their PMIC wrapper interface, a high-level interface
   for talking to the system PMIC over a dedicated I2C interface.
 - Qualcomm SCM driver has been moved to drivers/firmware. It's used for CPU
   up/down and needs to be in a shared location for arm/arm64 common code.
 - Cleanup of ARM-CCI PMU code.
 - Anoter set of cleanusp to the OMAP GPMC code.
