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.

Changelog v2:
- Grammar fix: "s/PHY types can be/PHY types that can be"
- Drop quotes from around the string constants.

Changelog v4:
- Move the new PHY types definitions into the usb.yaml schema where the
  phy_type property is now defined.
