The TI SDKs for J7200 SoCs offer sample firmwares which could be run on these cores to demonstrate an "echo" IPC test. Those firmware require certain memory carveouts to be reserved from system memory, timers to be reserved, and certain mailbox configurations for interrupt based messaging. These configurations could be different for a different firmware. While DT is not meant for system configurations, at least refactor these configurations from board level DTS into a dtsi for now. This dtsi for TI IPC firmware is board-independent and can be applied to all boards from the same SoC Family. This gets rid of code duplication and allows more freedom for users developing custom firmware (or no firmware) to utilize system resources better; easily by swapping out this dtsi. To maintain backward compatibility, the dtsi is included in all boards.
