Merge tag 'at91-cleanup' of git://github.com/at91linux/linux-at91 into next/soc

Merge "at91: cleanup for 3.16 #1" from Nicolas Ferre:

First cleanup series for 3.15
- localize GPIO header in mach-at91 directory
- big update on the CCF front with main and slow clocks
- a cleanup of ADC and touchscreen driver with unification on IIO and
  removal of old driver

[olof: Most of this branch is new code, not cleanups, so I'm merging this into
the SoC branch in spite of the branch name]
