Merge branch 'versatile/multiplatform' into next/multiplatform 



Merge "ARM Versatile multi-platform support" from Rob Herring:

Arnd lit a fire under me to dust this off and get it merged. So here it
is. The main change from prior version is I merged all the code to a
single file. It's a bigger patch than I'd like, but I don't think trying
to do it in multiple steps is worth it.

This is dependent on some solution for the default platform choice on
!MMU builds (allnoconfig) as it can't be Versatile after this series.
Arnd has some ideas on how to address that.

This is tested under QEMU. Linus previously tested this on actual h/w
and had a problem with the display identification which needs
investigation or agreement to worry about it if and when someone
actually cares.

* versatile/multiplatform:
  ARM: versatile: convert to multi-platform
  ARM: versatile: merge mach code into a single file
  ARM: versatile: switch to DT only booting and remove legacy code
  ARM: versatile: add DT based PCI detection
