6.6-stable review patch. If anyone has any objections, please let me know.

commit d33724ffb743d3d2698bd969e29253ae0cff9739 upstream.
It's expected that we'll encounter temporary exceptions during aux transactions. Adjust logging from drm_info to drm_dbg_dp to prevent flooding with unnecessary log messages.
