We already have function to configure PF (or VF) scheduling priority on a single GT, but we also need function that will cover all tiles and GTs. However, due to the current GuC FW limitation, we can't always rely on per-GT function as it actually only works for the PF case. The only way to change VFs scheduling priority is to use 'sched_if_idle' policy KLV that will change priorities for all VFs (and the PF). We will use these new functions in the upcoming patches.
