This is because the interface between interconnect and module is
standardized (Open Core Protocol), so it doesn't really matter which
interconnect technology is used.
Also, afaik sysc mostly just concerns the interaction between module and
PRCM. The only role the interconnect plays here is that it participates
in the OCP Disconnect Protocol to allow the module to safely disconnect
itself when it or the interconnect enters idle state.
