configs: am65x_evm_a53: Enhance bootcmd to start remoteprocs

The A53 U-boot can support early booting of the MCU R5F remote processor(s)
from U-boot prompt to achieve various system usecases before booting the
Linux kernel. Update the default BOOTCOMMAND to provide an automatic and
easier way to start the MCU R5F cores through added environment variables.
