ARM: SoC driver updates

Browse source 
Some of the larger changes this merge window:
  - Removal of drivers for Exynos5440, a Samsung SoC that never saw
    widespread use.
  - Uniphier support for USB3 and SPI reset handling
  - Syste control and SRAM drivers and bindings for Allwinner platforms
  - Qualcomm AOSS (Always-on subsystem) reset controller drivers
  - Raspberry Pi hwmon driver for voltage
  - Mediatek pwrap (pmic) support for MT6797 SoC
