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.
