Subject: [PATCH v4 1/5] dt-bindings: interconnect: Update property for icc-rpm path tag

To support path tag in icc-rpm driver, the "#interconnect-cells"
property is updated as enumerate values: 1 or 2. Setting to 1 means
it is compatible with old DT binding that interconnect path only
contains node id; if set to 2 for "#interconnect-cells" property, then
the second specifier is used as a tag (e.g. vote for which buckets).
