drm/i915: GuC-specific firmware loader
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]
