[PATCH v3 2/7] arm64: dts: ti: k3-j721e-som-p0: Switch MAIN R5F clusters to Split-mode

The TI J721E EVM board has 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.
