arm64: dts: ti: k3-j721e-beagleboneai64: Add missing cfg for TI IPC FW



The TI IPC Firmwares running on J721E SoCs use certain MAIN domain
timers as tick. Reserve those at board level DT to avoid remote
processor crashes. This config aligns with other J721E boards and can
be refactored out later.
