Merge tag 'at91-4.4-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux into fixes

Merge "Second fixes for 4.4" from Alexandre Belloni:

- fix of a hardware setup that prevents the sd/mmc interface to show up on
  sama5d2.
- proper selection of pinctrl drivers. PIO4 is necessary for the sama5d2 to
  boot.
