dt-bindings: phy: qcom: Relax required supplies

This commit relaxes the requirement for three regulator supplies in the QUSB2
PHY binding for legacy IPQ6018 nodes that do not describe board rails.

[Severity: Medium]
Does this unintentionally relax the schema requirements for IPQ5210?

Since qcom,ipq5210-qusb2-phy falls back to qcom,ipq6018-qusb2-phy, an IPQ5210
device tree node's compatible array will contain qcom,ipq6018-qusb2-phy.

The 'contains: enum' logic matches this fallback, which seems like it might
incorrectly apply this legacy IPQ6018 exemption to IPQ5210 nodes, allowing
them to silently pass schema validation without the required regulator
supplies.
