Subject: [PATCH v4 1/3] dt-bindings: interconnect: Add Qualcomm IPQ9574 support

Add interconnect-cells to clock provider so that it can be
used as icc provider.

Add master/slave ids for Qualcomm IPQ9574 Network-On-Chip
interfaces. This will be used by the gcc-ipq9574 driver
that will for providing interconnect services using the
icc-clk framework.
