[PATCH] drm/i915: use for_each_intel_connector_iter in intel_display.c

[Daniel Vetter <daniel.vetter@ffwll.ch>]

This gets rid of the last users of for_each_intel_connector(), remove
that too.

The one exception is the loop in verify_encoder_state - that needs to
switch over to for_each_connector_in_state.

v2: Maarten corrected me that in the state verifier we indeed must
only walk connectors in the atomic commit, not all of them!
