arm: dts: k3-am65: Fix up MCU R5FSS cluster mode back to Split-mode
The default U-Boot environment variables and design are all set up to
have the MCU R5FSS cluster 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 mode for the cluster got switched back to LockStep mode by mistake
in commit e49787634312 ("arm: dts: k3-am65: 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@41400000: Invalid op: Trying to start secondary core 2 in lockstep mode
Load Remote Processor 1 with data@addr=0x82000000 65268 bytes: Failed!
Fix this by switching back the cluster to the expected Split-mode.
Make this mode change in the u-boot specific dtsi file to avoid such
sync overrides in the future until the kernel dts is also switched to
Split-mode by default.
