drm/i915/guc: Add preemption action to GuC firmware interface
We're using GuC action to request preemption. However, after requesting preemption we need to wait for GuC to finish its own post-processing before we start submitting our requests. Firmware is using shared context to report its status. Let's update GuC firmware interface with those new definitions. v2: Drop unused INTEL_GUC_PREEMPT_OPTION_IMMEDIATE Signed-off-by:Michał Winiarski <michal.winiarski@intel.com> Cc: Jeff McGee <jeff.mcgee@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Oscar Mateo <oscar.mateo@intel.com> Reviewed-by:
