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

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.
