arm64: dts: ti: Refractor AM625 SK dts
To prepare for upcoming derivative boards based on the AM625 SK, refactor the dts file for this board into a common dtsi file that the derivative boards will inherit and retain only those parts that are different in the current dts file. Signed-off-by: Anand Gadiyar <gadiyar@ti.com> Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Link: https://lore.kernel.org/r/20230321-am62-lp-sk-v2-2-0a56e1694804@ti.com Signed-off-by: Nishanth Menon <nm@ti.com>
