From: Xin Ji <xji@analogixsemi.com>

[ Upstream commit a77c2af0994e24ee36c7ffb6dc852770bdf06fb1 ]

As V4L2_FWNODE_BUS_TYPE_PARALLEL not properly descript for DPI
interface, this patch use new defined V4L2_FWNODE_BUS_TYPE_DPI for it.

Fixes: fd0310b6fe7d ("drm/bridge: anx7625: add MIPI DPI input feature")
