This patch series adds support for realtime group priority and exposes
allowed priorities info with a new dev query.

Those changes are required to implement EGL_IMG_context_priority and
EGL_NV_context_priority_realtime extensions properly.

This patch series assumes that [1] is applied. (found in drm-misc-fixes)

The Mesa MR using this series is available here [2].

v2:
- Add Steven Price r-b on the first patch
- Remove drm_panthor_group_allow_priority_flags definition and document
  that allowed_mask is a bitmask of drm_panthor_group_priority on the
  second patch

v3:
- Use BIT macro in panthor_query_group_priorities_info
- Add r-b from Steven Price and Boris Brezillon
