This implements suspend/resume using the atomic update supsend/resume helpers instead of the current implementation which uses regcache. The code has been tested on a Colibri VF61 using the freeze suspend mode.
This version is a rebase ontop of the fix for the regmap cache issue: https://lists.freedesktop.org/archives/dri-devel/2016-June/109625.html
Dave, Thierry: Could you have a look at patch 1? If that looks good for you I will take it through my tree...
