[PATCH 00/14] drm/radeon: uvd/vce cleanup and fix for hibernation

So all patches does not change the logic or outcome (from hw register write point of view) only what error messages get printed on failure.

Patch 13 just add a new flag to asic reset so we can force hard reset.

Patch 14 takes advantages of that for the hibernation case and hard reset during freeze. It seems to works well for several hibernation cycles (both real hibernation and also when using PM_DEBUG facilities).

All this was only test on southern island laptop (si), i did however read over and over the various patches to check that i did not change behavior. I splitted them for each asic generation to make bisection easier in the unlikely case that i did miss something.

Please review.

Cheers, Jérôme
