[PATCH v6 04/19] 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.

- Grammar fix: "s/PHY types can be/PHY types that can be"
- Drop quotes from around the string constants.
- Move the new PHY types definitions into the usb.yaml schema where the
phy_type property is now defined.
