The default U-Boot environment variables and design are all set up for
both the MAIN R5FSS clusters to be in Split-mode. This is the setting
in v2021.01 U-Boot and the dt nodes are synched with the kernel binding
property names in commit 468ec2f3ef8f ("remoteproc: k3_r5: Sync to
upstreamed kernel DT property names") merged in v2021.04-rc2.
The modes for both the clusters got switched back to LockStep mode by
mistake in commit 70e167495ab2 ("arm: dts: k3-j721e: Sync Linux v5.11-rc6
dts into U-Boot") also in v2021.04-rc2. This throws the following warning
messages when early-booting the cores using default env variables,
k3_r5f_rproc r5f@5d00000: Invalid op: Trying to start secondary core 7 in
lockstep mode
Load Remote Processor 3 with data@addr=0x82000000 98484 bytes: Failed!
k3_r5f_rproc r5f@5f00000: Invalid op: Trying to start secondary core 9 in
lockstep mode
Load Remote Processor 5 with data@addr=0x82000000 98484 bytes: Failed!
Fix this by switching back both the clusters to the expected Split-mode.
Fixes: 70e167495ab2 ("arm: dts: k3-j721e: Sync Linux v5.11-rc6 dts into U-Boot")
