product/rdn2: update cross chip CCG connections for RD-N2 Multichip

RD-N2 Multichip variant mesh has been updated with total CCG count of
five per chip and the connections between the chips has been modified.
Out of the five CCGs, four CCGs are used for the cross chip connection
and one for the CXL device.

This patch updates the CMN-700 CCG config data with the updated
connections. Since there are only four CCG used for cross chip
connections and one CCG left for CXL device, use CCG_PER_CHIP instead of
RNF_PER_CHIP for calculating the HAID value of the CCG nodes to avoid
overlapping HAIDs between two or more chips.
