Pull ARM SoC driver updates from Olof Johansson:
 "This 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"
