arm64: dts: ti: k3-j7200-som: Describe OSPI and Hyperflash partition info

Browse Source 
Describe OSPI and Hyperflash 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. J7200 SoM 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 SoM also has a 64 MiB Hyperflash present on it, the partition names
and offsets are chosen according to the corresponding name and offsets
in bootloader.
