drm/i915/guc: Add host2guc notification for suspend and resume
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.
