Merge branch 'cns3xxx/multiplatform' into next/multiplatform

I've looked at all the platforms recently to see what their
state is. cns3xxx seems quite clean but not very actively
maintained. Since it is really easy to convert to multiplatform,
that's what I did here.

* cns3xxx/multiplatform:
  ARM: cns3xxx: initial DT support
  ARM: cns3xxx: enable multiplatform support
  ARM: cns3xxx: move debug_ll code to include/debug/
  ARM: cns3xxx: enable sparse IRQ support
  ARM: cns3xxx: make mach header files local
