arm: dts: renesas: Clean up RPC DT nodes

Remove duplicate properties which are present both in arch/arm/dts/
and upstream dts/upstream/src/arm64/renesas/ in favor of those in
upstream DTs. Since those are duplicates, this causes no functional
change. Remove unused num-cs and bank-width DT properties.
