Pull ARM driver updates from Arnd Bergmann:
 "These are the usual updates for SoC specific device drivers and
  related subsystems that don't have their own top-level maintainers:

   - ARM SCMI/SCPI updates to allow pluggable transport layers

   - TEE subsystem cleanups

   - A new driver for the Amlogic secure power domain controller

   - Various driver updates for the NXP Layerscape DPAA2, NXP i.MX SCU
     and TI OMAP2+ sysc drivers.

   - Qualcomm SoC driver updates, including a new library module for
     "protection domain" notifications

   - Lots of smaller bugfixes and cleanups in other drivers"
