Merge branch 'testing/bcmring' into next/cleanups 

This attempts to get the bcmring platform better in line with the
other platforms. Moving the header files below mach/ helps with
the future reorganization for multiplatform kernels, and using
MMIO accessors is generally the right thing.

* testing/bcmring:
  ARM: bcmring: use proper MMIO accessors
  ARM: bcmring: remove include/csp/ subdir
  ARM: bcmring: move cfg_global header to mach/
