Subject: [PATCH 12/14] drm/imx: dc-lb: Drop initial primary and secondary
 input selections

It's unnecessary to set initial primary and secondary input selections
because KMS driver would do that when doing atomic commits.  Drop the
selections.  This is needed as a preparation for reading LayerBlend
secondary input selection when trying to disable CRTC at boot in an
upcoming commit.
