2024-01-05drm/xe/guc: Add helpers for HXG messagesMichal Wajdeczko1-0/+108
In addition to MMIO and CTB communication between the host driver and the GUC firmware, we will start using GuC HXG message protocol in communication between SR-IOV VFs and PF. Define helpers related to HXG message protocol to minimize code duplication.
