ARM: driver updates

Browse source 
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
