Describe OSPI and QSPI 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 SoM has a MT35 64 MiB OSPI flash and MT25 64 MiB QSPI flash both with sector size of 128 KiB thus the size of the smallest partition is chosen as 128KiB, the partition names and offsets are chosen according to the corresponding name and offsets in bootloader.
