[Intel-xe] [PATCH v2 0/9] DRM scheduler changes for Xe

[Matthew Brost <matthew.brost@intel.com>]

As a prerequisite to merging the new Intel Xe DRM driver [1] [2], we
have been asked to merge our common DRM scheduler patches first.

This a continuation of a RFC [3] with all comments addressed, ready for
a full review, and hopefully in state which can merged in the near
future. More details of this series can found in the cover letter of the
RFC [3].

These changes have been tested with the Xe driver.

v2:
 - Break run job, free job, and process message in own work items
 - This might break other drivers as run job and free job now can run in
   parallel, can fix up if needed
