ARM: SoC driver updates

Browse source 
This branch contains platform-related driver updates for ARM and ARM64.
 
 Highlights:
  - ARM SCMI (System Control & Management Interface) driver cleanups
  - Hisilicon support for LPC bus w/ ACPI
  - Reset driver updates for several platforms: Uniphier,
  - Rockchip power domain bindings and hardware descriptions for several SoCs.
  - Tegra memory controller reset improvements
