[PATCH 12/22] drm/i915/guc: Pass intel_guc struct parameter to intel_guc_suspend/resume

[Sagar Arun Kamble]

GuC suspend/resume functions are GuC specific functions hence update the
parameter from dev_priv to intel_guc struct.

v2: Reverted s/dev_priv/i915. Updated commit message. (Michal Wajdeczko)
Rebase.
