dt-bindings: interconnect: qcom,sm6350-rpmh: Add clocks for QoS

Add the clocks for some interconnects to the bindings that are required
to set up the QoS correctly. Update one of the examples to aggre2_noc to
have an example with clocks.

Also while we're at it, remove #interconnect-cells: true as that's
already provided from qcom,rpmh-common.yaml.
