If it's a mxs-phy specific property, we may need to have vendor prefix
'fsl,' for it.
I see you set the property in imx6qdl.dtsi. Is it true that we should
always set it for imx6q/dl? If yes, why cannot we have the driver to
force it for imx6q type of phy. If no, where do we need to set it and
where not?
