ARM: SoC fixes for 4.15-rc 

ARM SoC fixes for this merge window:
 
  - A revert of all SCPI changes from the 4.15 merge window. They had
    regressions on the Amlogic platforms, and the submaintainer isn't
    around to fix these bugs due to vacation, etc. So we agreed to revert
    and revisit in next release cycle.
 
  - A series fixing a number of bugs for ARM CCN interconnect, around
    module unload, smp_processor_id() in preemptable context, and fixing
    some memory allocation failure checks.
 
  - A handful of devicetree fixes for different platforms, fixing
    warnings and errors that were previously ignored by the compiler.
 
  - The usual set of mostly minor fixes for different platforms.

Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC fixes from Olof Johansson:

 - A revert of all SCPI changes from the 4.15 merge window. They had
   regressions on the Amlogic platforms, and the submaintainer isn't
   around to fix these bugs due to vacation, etc. So we agreed to revert
   and revisit in next release cycle.

 - A series fixing a number of bugs for ARM CCN interconnect, around
   module unload, smp_processor_id() in preemptable context, and fixing
   some memory allocation failure checks.

 - A handful of devicetree fixes for different platforms, fixing
   warnings and errors that were previously ignored by the compiler.

 - The usual set of mostly minor fixes for different platforms.
