Subject: [PATCH v3 3/7] arm64: dts: ti: k3-j721e-sk: Switch MAIN R5F clusters to Split-mode

The TI J721E SK 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.
