Subject: [PATCH v3 22/33] arm64: dts: ti: k3-j721e-beagleboneai64: Switch MAIN R5F clusters to Split-mode

Switch the MAIN domain R5F clusters into split mode to maximize the
number of R5F processors. The TI IPC firmware for the split processors
is already available public. This config aligns with other J721E boards
and can be refactored out later.
