drm/i915: Implementation of GuC submission client
A GuC client has its own doorbell and workqueue. It maintains the
doorbell cache line, process description object and work queue item.
A default guc_client is created for the i915 driver to use for
normal-priority in-order submission.
Note that the created client is not yet ready for use; doorbell
allocation will fail as we haven't yet linked the GuC's context
descriptor to the default contexts for each ring (see later patch).
v2:
Defer adding structure members until needed [Chris Wilson]
Rationalise type declarations [Chris Wilson]
v5:
Add GuC per-engine submission & seqno statistics.
Move wq locking to encompass both get_space() and add_item().
Take forcewake lock in host2guc_action() [Tom O'Rourke]
v6:
Fix GuC doorbell cacheline selection code (the
cacheline-within-page calculation was wrong).
Rename GuC priorities to make them closer to the names used in
the GuC firmware source, matching what the autogenerated
versions will (probably) be.
Add per-ring statistics to client.
