Subject: [PATCH 0/4] Switch MAIN R5F clusters to Split-mode for TI SoCs

TI SoCs (J7200, J721E, J721S2 & J784S4) have multiple R5F clusters in
the MAIN domain. All of these clusters 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. 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.
