feat(neoverse-rd): add multichip pas entries

RD-Fremont-Cfg2, the quad-chip variant of RD-Fremont supports 8 DRAM
banks compared to RD-Fremont and RD-Fremont-Cfg1, which only support 2.
Therefore, define PAS entry mappings for all the DRAM banks, so that
they could be utilized on the multichip variant.
