Subject: [PATCH v2 3/4] arm64: dts: ti: k3-j721s2-main: Switch MAIN R5F clusters to Split-mode

J721S2 SoCs have two R5F clusters in the MAIN domain, and both of these
are configured for LockStep mode at the moment. Switch both of these R5F
clusters to Split mode by default to maximize the number of R5F cores.
