arm64: dts: ti: k3-am654-baseboard: Describe OSPI flash partition info

Browse Source 
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. AM654 baseboard has a MT35XU512ABA
64 MiB OSPI flash with sector size of 128 KiB thus the size of the
smallest partition is chosen as 128 KiB, the partition names and
offsets are chosen according to the corresponding name and offsets
in bootloader.
