    What is "t-phy"? Perhaps you should have used just "phy" here...

At first I use "phy", but it causes dt_binding_check fail:
"'#phy-cells' is a required property"

Due to we only need add '#phy-cells' for each subnode (usb-phy, pcie-phy
or sata-phy), but not for parent one, I change the parent node name as
"t-phy" which is a glue layer node, not a real phy.
I also prefer to "phy", but seems dt_binding_check can't distinguish
this case.

Thanks
