drm/i915/guc: Implement GuC context operations for new inteface
Implement GuC context operations which includes GuC specific operations
alloc, pin, unpin, and destroy.
v2:
(Daniel Vetter)
- Use msleep_interruptible rather than cond_resched in busy loop
(Michal)
- Remove C++ style comment
v3:
(Matthew Brost)
- Drop GUC_ID_START
(John Harrison)
- Fix a bunch of typos
- Use drm_err rather than drm_dbg for G2H errors
(Daniele)
- Fix ;; typo
- Clean up sched state functions
- Add lockdep for guc_id functions
- Don't call __release_guc_id when guc_id is invalid
- Use MISSING_CASE
- Add comment in guc_context_pin
- Use shorter path to rpm
(Daniele / CI)
- Don't call release_guc_id on an invalid guc_id in destroy
v4:
(Daniel Vetter)
- Add FIXME comment
