Subject: [PATCH v3 1/7] arm64: dts: ti: k3-j7200-som-p0: Switch MAIN R5F cluster to Split-mode

The TI J7200 EVM board has one R5F cluster in the MAIN domain, and it is
configured for LockStep mode at the moment. Switch the MAIN R5F cluster
to Split mode by default to maximize the number of R5F cores.
