[PATCH v2 08/15] v4l: vsp1: Replace manual DRM pipeline input setup in vsp1_du_setup_lif

[Laurent Pinchart]

The vsp1_du_setup_lif() function sets up the DRM pipeline input
manually. This duplicates the code from the
vsp1_du_pipeline_setup_input() function. Replace the manual
implementation by a call to the function.

As the pipeline has no enabled input in vsp1_du_setup_lif(), the
vsp1_du_pipeline_setup_input() function will not setup any RPF, and will
thus not setup formats on the BRU sink pads. This isn't a problem as all
inputs are disabled, and the BRU sink pads will be reconfigured from the
atomic commit handler when inputs will be enabled.
