[PATCH 1/1][SRU][Jammy] drm/amd/display: Avoid flooding unnecessary info messages

[You-Sheng Yang]

From: Wayne Lin <Wayne.Lin at amd.com>

BugLink: https://bugs.launchpad.net/bug/2115238

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.

Fixes: 3637e457eb00 ("drm/amd/display: Fix wrong handling for AUX_DEFER case")
