fix(rdn2): add LCA multichip data for RD-N2-Cfg2

Browse source 
This patch adds the routing table addresses required for LCA
enablement on RD-N2-Cfg2. CMN on RD-N2-Cfg2 uses AXI Stream IDs
to route LCA connections to the correct downstream tx_cxs_a4s
port. The data programmed in the routing table are the A4S IDs
of each chip.
