Describe OSPI flash partition information through device tree, this helps to remove passing partition information through the mtdparts commandline parameter which requires maintaining the partition information in a string format. J721E SK has a S28 64 MiB OSPI flash with sector size of 256 KiB thus the size of the smallest partition is chosen as 256 KiB, the partition names and offsets are chosen according to the corresponding name and offsets in bootloader.
