board: phycore-imx93: env: Move fdt and bootenv addresses

Move the load addresses for FDTs and bootenv.txt to create space for
loading OS image. Otherwise, parts of the image might get corrupted.
and the following boot error will be present:

  ERROR: FDT image overlaps OS image (OS=80400000..832a0000)

Moreover, this commit also syncs addresses with downstream PHYTEC
u-boot for i.MX93 in preparation for FIT image support in the future.
