[PATCH RFC 1/4] dt-bindings: clock: qcom,sm8550-tcsr: Add QREF regulator supplies for glymur

[Qiang Yu <qiang.yu@oss.qualcomm.com>]

The glymur TCSR PCIe clkref clocks require regulator supplies for the
QREF block and its refgen reference voltage generator. Add the optional
supply properties restricted to qcom,glymur-tcsr via an allOf/if/then
conditional schema.

Switch from additionalProperties to unevaluatedProperties so that
properties defined inside the if/then block are correctly recognised as
evaluated and not rejected by the schema validator.
