[PATCH v2] dt-bindings: phy: qcom: Relax required supplies

[Rob Herring (Arm)]

For the QUSB2 PHY binding, keep the three regulator supplies required
except for legacy IPQ6018 nodes that do not describe the board rails.

This relaxes the requirements for the IPQ5210 as well as if it is
compatible with IPQ6018, then it shouldn't have more required
properties either.
