Update crtc retrieval from dpu_enc to drm_enc, since new links get set
as part of the update legacy mode set. The dpu_enc->crtc cache is no
more needed, hence cleaning it as part of this change.
NAK. Quoting the documentation:
only really meaningful for non-atomic drivers. Atomic drivers should
instead check &drm_connector_state.crtc.
Please adjust according to the documentation.
