Also, We plan to use intel_guc_suspend and intel_guc_resume through intel_uc_suspend and intel_uc_resume in the path i915_drm_suspend and i915_drm_resume respectively for better naming. Also, with this patch we pass intel_guc struct as parameter to enter_sleep and exit_sleep functions. Moved the definition to intel_guc.c for better code structuring. If needed we can pull some of the functions from intel_guc.c to new file intel_guc_pm.c in future.
