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?
