dt-bindings: usb: Add "ulpi/serial/hsic" PHY types 



Aside from the UTMI+ there are also ULPI, Serial and HSIC PHY types
that can be specified in the phy_type HCD property. Add them to the
enumeration of the acceptable values.

      Tells USB controllers that we want to configure the core to support a

      UTMI+ PHY with an 8- or 16-bit interface if UTMI+ is selected. In case

      this isn't passed via DT, USB controllers should default to HW

      capability.

      UTMI+ PHY with an 8- or 16-bit interface if UTMI+ is selected, UTMI+ low

      pin interface if ULPI is specified, Serial core/PHY interconnect if

      serial is specified and High-Speed Inter-Chip feature if HSIC is

      selected. In case this isn't passed via DT, USB controllers should

      default to HW capability.
