[Intel-gfx] [PATCH v2 3/6] drm/i915/guc: Update name and prototype of GuC submission interface functions

[Sagar Arun Kamble]

i915 GuC submission is hardware interface and GuC APIs that are not user
facing should be named intel_guc* hence we change GuC submission related
functions name prefix to intel_guc. Also changed the parameter to these
functions to intel_guc struct.

v2: Using local guc variable in intel_uc_fini_hw. (Michal Wajdeczko)
Rebase.
