J784S4 SoCs have three R5F clusters in the MAIN domain, and all 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. The MCU R5F cluster continues to be in the preferred
LockStep mode.

Note that this configuration is the default for remoteproc mode (kernel
driver boots the R5F processors). These will be overridden for early-booted
remoteprocs through the corresponding IPC-only support in the K3 R5F
remoteproc driver.
