Subject: [PATCH v1 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 doesn't
contain tag, if set to 2 for "#interconnect-cells" property, then the
second specifier in the interconnect path indicates the voting is for
which buckets.
