  Add USB superspeed qmp phy node to dtsi.

Make sure that the various board dts files (which include sm4250.dtsi file)
continue to work as intended.

Please excuse me if I'm wrong, but this will not work with the current

Oh.. from your previous emails, I got the feeling that you were
already reworking the existing PHY driver as part of enabling it for
newer bindings.

No issues, I will send the PHY patches as well in the next version.
