Cover letter [PATCH 0/7] Per context dynamic (sub)slice power-gating

From: Tvrtko Ursulin <[email protected]>

Re-send of the old series with the following highlights:

* Rebased for drm-tip changes, mostly IS_GEN changes.
* New patch adding some selftests for the feature. (Since majority of test code has been removed from the IGT.)
