On a imx6q-wandboard the following warnings are observed:

[    4.327794] video-mux 20e0000.iomuxc-gpr:ipu1_csi0_mux: bad remote port 
parent
[    4.336118] video-mux 20e0000.iomuxc-gpr:ipu2_csi1_mux: bad remote port 
parent

As explained by Philipp Zabel:

"There are empty endpoint nodes (without remote-endpoint property)
labeled ipu1_csi[01]_mux_from_parallel_sensor in the i.MX6 device trees
for board DT implementers' convenience. See commit 2539f517acbdc ("ARM:
dts: imx6qdl: Add video multiplexers, mipi_csi, and their connections")."

So demote the warning to debug level and make the wording a bit
less misleading.
