drm/i915/display: add a gelper to relative data rate handling

Browse source

Add a helper to the relative data rate handling in skl_watermarks.c
where other similar functions are implemented. Also get rid of
use_min_ddb() and use use_minimal_wm0() instead to decide whether
the relative data rate can be returned as 0
