drm/i915/guc: Introduce guc_is_ready
We already have guc_is_running function, but it only reflects firmware status, while to fully use GuC we need to know if we've already established communication with it. v2: also s/intel_guc_is_running/intel_guc_is_fw_running (Chris) Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20200131153706.109528-1-michal.wajdeczko@intel.com
