drm/i915: Fix wrong CDCLK adjustment changes
Previous patch didn't take into account all pipes
but only those in state, which could cause wrong
CDCLK conclcusions and calculations.
Also there was a severe issue with min_cdclk being
assigned to 0 every compare cycle.
Too bad this was found by me only after merge.
This could be also causing the issues in test, however
not clear - anyway marking this as fixing the
"Adjust CDCLK accordingly to our DBuf bw needs".
v2: - s/pipe/crtc->pipe/
- save a bit of instructions by
skipping inactive pipes, without
getting 0 DBuf slice mask for it.
