Subject: [PATCH 3/3] dt-bindings: interconnect: split SM8450 to own schema
SM8450 comes with interconnects having and missing IO address space, and
variable number of clocks, so split it from common file for easier
maintenancen and to fix warnings like:
sm8450-hdk.dtb: interconnect-0: 'reg' is a required property
