Allwinner DT changes for 4.9, take 2

Browse Source 
A second set of device tree changes, this time switching a few SoCs to the
 new sunxi-ng clock framework. We also added the support for a new SoC
 (NextThing GR8 and its evaluation board), and the support for the DRM
 driver in the A33.

Merge tag 'sunxi-dt-for-4.9-2' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux into next/late

Merge "Allwinner DT changes for 4.9, take 2" from Maxime Ripard:

A second set of device tree changes, this time switching a few SoCs to the
new sunxi-ng clock framework. We also added the support for a new SoC
(NextThing GR8 and its evaluation board), and the support for the DRM
driver in the A33.

To maintain bisectability, while avoiding some un-trivial merge
conflicts, I had to merge the clk branch that I've sent a PR to Mike
and Stephen. This branch will of course be stable.
