Add host2guc interface to notify GuC power state changes when
enter or resume from power saving state.
v3: Move intel_guc_suspend to i915_drm_suspend for consistency.
v2: Add GuC suspend/resume to runtime suspend/resume too
v1: Change to a more flexible way when fill host to GuC scratch
data in order to remove hard coding.

GuC expects two bits for Render and Media domain separately when
driver sends data via host2guc SAMPLE_FORCEWAKE. Bit 0 is for
Render and bit 1 is for Media domain.
v2: Keep sync with code for WaRsDoubleRc6WrlWithCoarsePowerGating
v1: Add parameters definition to avoid magic value

The firmware layout changes that now it only has css header +
uCode + RSA signature. Plus, other trivial changes to support
GuC V4.3.

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.

This fetches the required firmware image from the filesystem,
then loads it into the GuC's memory via a dedicated DMA engine.
This patch is derived from GuC loading work originally done by
Vinit Azad and Ben Widawsky.
v2:
Various improvements per review comments by Chris Wilson
v3:
Removed 'wait' parameter to intel_guc_ucode_load() as firmware
prefetch is no longer supported in the common firmware loader,
per Daniel Vetter's request.
Firmware checker callback fn now returns errno rather than bool.
v4:
Squash uC-independent code into GuC-specifc loader [Daniel Vetter]
Don't keep the driver working (by falling back to execlist mode)
if GuC firmware loading fails [Daniel Vetter]
v5:
Clarify WOPCM-related #defines [Tom O'Rourke]
Delete obsolete code no longer required with current h/w & f/w
[Tom O'Rourke]
Move the call to intel_guc_ucode_init() later, so that it can
allocate GEM objects, and have it fetch the firmware; then
intel_guc_ucode_load() doesn't need to fetch it later.
[Daniel Vetter].
v6:
Update comment describing intel_guc_ucode_load() [Tom O'Rourke]

intel_guc_fwif.h contains the subset of the GuC interface that we
will need for submission of commands through the GuC. These MUST
be kept in sync with the definitions used by the GuC firmware, and
updates to this file will (or should) be autogenerated from the
source files used to build the firmware. Editing this file is
therefore not recommended.
i915_guc_reg.h contains definitions of GuC-related hardware:
registers, bitmasks, etc. These should match the BSpec.
v2:
Files renamed & resliced per review comments by Chris Wilson
v4:
Added DON'T-EDIT-ME warning [Tom O'Rourke]
