usb: ehci/ohci-platform: assigned hcd phy phandle at platform probe

Browse Source 
In ehci/ohci-platform, phy_power_on() gets called twice at probe time,
one is at pdata->power_on(); another is in usb_add_hcd(). However,
phy_power_off() is only invoked one time when ehci/ohci-platform goes
to PM suspend. As a result, the phy power count become inconsistent.

This adds assigned phy phandle to hcd-phy at ehci/ohci-platform probe
time to prevent hcd invoking generic phy methods again when phy-cells
is 0 in DT.
