drm/i915: Use drm_connector_list_iter in debugfs
While at it also try to reduce the locking a bit to what's really just
needed instead of everything that we could possibly lock.
Added a new for_each_intel_connector_iter which includes the cast to
intel_connector.
Otherwise just plain transformation with nothing special going on.
v2: Review from Maarten:
- Stick with modeset_lock_all in sink_crc, it looks at crtc->state.
- Fix up early loop exit in i915_displayport_test_active_write.
v3: Rebase onto the iter_get/put->iter_begin/end rename.
