[PATCH v3 1/3] dt-bindings: interconnect: qcom,qcs615-rpmh: add clocks property to enable QoS

[Odelu Kukatla]

Aggre1-noc interconnect node on QCS615 has QoS registers located
inside a block whose interface is clock-gated. Accessing these
registers requires the corresponding clock(s) to be enabled.
Update the bindings to include the 'clocks' property.

Ensure that only aggre1-noc interconnect node uses this property
by explicitly forbidding it for all other interconnect nodes.
