We should still keep a separate entry for the phy in the dtsi
files. And the phy should be a child of the scm_conf area in the
dtsi file.

This is because the scm and usb_otg_hs are separate devices and
can be clocked separately. So the phy driver needs to be a
separate driver to avoid spaghetti code and issues with clocking.
