    phy: sun4i-usb: Call phy_passby even for PHY#0

    On newer Allwinner SoC, there is a pair of EHCI/OHCI USB hosts
    for OTG host mode. USB PHY passby must be configured for its
    corresponding PHY. so we can call for PHY#0. on the other hand
    in past usb-phy code the same thing can be restricted for
    Lower SoC's, other than H3/H5/A64.

    Now there is no need to restrict usb passby since the phy driver
    is DT enabled, and the respective phy calls will trigger based
    DT information initiated by the drivers.
