[PATCH v2 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. For that node,
driver must enable the corresponding clock(s) before accessing
the registers. Add the 'clocks' property so the driver can obtain
and enable the required clock(s).

Only interconnects that have clock‑gated QoS register interface
use this property; it is not applicable to all interconnect nodes.
