Subject: [PATCH 5.19 1139/1157] Revert "drm/bridge: anx7625: Use DPI bus type"

From: Robert Foss <robert.foss@...aro.org>

commit 61922beba36adea8702fe8069b309c806f6608af upstream.

This reverts commit a77c2af0994e24ee36c7ffb6dc852770bdf06fb1.

This patch depends on the patches just aplied to the media tree, and will
not build without them, which leaves drm-misc-next in a broken state.
Let's revert the two latter patches until rc1 has been branched,
and rc1 has been backmerged into drm-misc-next.
