Renamed intel_guc_suspend to intel_guc_enter_sleep and intel_guc_resume
to intel_guc_exit_sleep to match GuC nomenclature compatibility. 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.
