[PATCH v3 2/3] regulator: dt-bindings: qcom,sdm845-refgen-regulator: Document IPQ9650

[Kathiravan Thirumoorthy]

IPQ9650 has two REFGEN blocks which provide reference current to the PCIe,
USB and UNIPHY PHYs. Unlike other supported platforms, IPQ9650 requires the
REFGEN clocks to be enabled explicitly.

Document the IPQ9650 compatible and the required clocks for it.

While at it, move the allOf block after the 'required' property section.
