[PATCH 1/3] dt-bindings: interconnect: qcom,x1e80100-rpmh: add clocks property to enable QoS

[Raviteja Laggyshetty]

Some interconnect nodes on X1E80100 have QoS registers located inside
a block whose interface is clock-gated. For those nodes, 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.
