Merge tag 'sti-dt-for-v3.16-1' of git://git.stlinux.com/devel/kernel/linux-sti into next/dt

Merge "ARM: STi: DT changes for v3.16, v3" from Maxime Coquelin:

Please consider these STi DT updates for v3.16.

This 3rd version takes into account Olof's comments on the v2:
        - Fix upper-cases in labels and node names
        - Sort compatibles order from specific to generic
        - Sort dts entries in Makefile

It also adds support for the B2020 revision E board for STiH416 SoC.

Note that two reset patches are part of this pull request, in order to avoid
compilation breakage.
Adding these two patches in this pull request has been accepted by Philipp Zabel.
