ARM: SoC driver updates for 4.17

The main addition this time around is the new ARM "SCMI" framework,
which is the latest in a series of standards coming from ARM to do power
management in a platform independent way. This has been through many
review cycles, and it relies on a rather interesting way of using the
mailbox subsystem, but in the end I agreed that Sudeep's version was
the best we could do after all.

Other changes include:

- the ARM CCN driver is moved out of drivers/bus into drivers/perf,
  which makes more sense. Similarly, the performance monitoring
  portion of the CCI driver are moved the same way and cleaned up
  a little more.

- a series of updates to the SCPI framework

- support for the Mediatek mt7623a SoC in drivers/soc

- support for additional NVIDIA Tegra hardware in drivers/soc

- a new reset driver for Socionext Uniphier

- lesser bug fixes in drivers/soc, drivers/tee, drivers/memory, and
  drivers/firmware and drivers/reset across platforms
