Subject: [PATCH v3 6/7] arm64: dts: ti: k3-j784s4-evm: Switch MAIN R5F clusters to Split-mode

The TI J784S4 EVM board has three R5F clusters in the MAIN domain, and
all of these are configured for LockStep mode at the moment. Switch
all of these R5F clusters to Split mode by default to maximize the
number of R5F cores.
