Subject: [PATCH v2 05/12] dt-bindings: interconnect: split SC8180x to own schema

SC8180x comes with interconnects having and missing IO address space, and
variable number of clocks, so split it from common file for easier
maintenance and to fix warnings like:

sc8180x-lenovo-flex-5g.dtb: interconnect-0: 'reg' is a required property
