product/rdn2: add mapping for cmn700 address space
Created by: adiang01
To allow access of the CMN700 register space from Request Nodes, add CMN700 address space as a RNSAM non-hashed region to route the accesses for CMN700 configuration registers to the correct destination node i.e HN-D node instead of DRAM.
