drm/i915/cdclk: Use enabled_pipes instead of active_pipes for the glk audio w/a

Currently we are considering the set of active pipes when
determining if we need to boost the cdclk due to glk audio
issues. Replace that with the set of logically enabled pipes
instead. That is generally how everything else cdclk related
is computed (cdclk_state->logical is based on logically
enabled pipes).
