Try to fix SAGV block time handling:
- zero means no SAGV
- avoid integer overflows
- slightly better debug logs
- assorted cleanups
v2: reorder to allow stable backport of the zero->no SAGV patch
Fix/clean some PSF GV stuff as well that caught my eye
Ville Syrjälä (8):
drm/i915: Treat SAGV block time 0 as SAGV disabled
drm/i915: Rework SAGV block time probing
drm/i915: Probe whether SAGV works on pre-icl
drm/i915: Reject excessive SAGV block time
drm/i915: Rename pre-icl SAGV enable/disable functions
drm/i915: Fix PSF GV point mask when SAGV is not possible
drm/i915: Unconfuses QGV vs. PSF point masks
