ARM: SoC driver updates for 4.16

A number of new drivers get added this time, along with many low-priority
 bugfixes. The most interesting changes by subsystem are:
 
 bus drivers:
   - Updates to the Broadcom bus interface driver to support newer SoC types
   - The TI OMAP sysc driver now supports updated DT bindings
 
 memory controllers:
   - A new driver for Tegra186 gets added
   - A new driver for the ti-emif sram, to allow relocating
     suspend/resume handlers there
 
 SoC specific:
   - A new driver for Qualcomm QMI, the interface to the modem on MSM SoCs
   - A new driver for power domains on the actions S700 SoC
   - A driver for the Xilinx Zynq VCU logicoreIP
 
 reset controllers:
   - A new driver for Amlogic Meson-AGX
   - various bug fixes
 
 tee subsystem:
   - A new user interface got added to enable asynchronous communication
     with the TEE supplicant.
   - A new method of using user space memory for communication with
     the TEE is added
