Merge tag 'at91-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91 into next/multiplatform

Merge "at91: multiplatform for 4.1 #1" from Nicolas Ferre:

This is the multi-platform support for AT91:
- reworked arch/arm/mach-at91/Kconfig and arch/arm/Kconfig to switch to
  multi-platform
- updated at91_dt_defconfig
- continue the cleanup of unneeded files and code chunks
