ccmp1: adjust memory layout for FIT image support 

This commit updates the memory layout to properly allocate space for the
different FIT image components, while ensuring total memory usage stays below
128 MiB. This avoids overlaps and ensures correct loading on memory-constrained
variants.

Final memory map:

  Start of memory:        #  0xC0000000
                          #   |
                          #   | 32 MiB reserved
                          #   v
  FIT image load address: #  0xC2000000
                          #   |
                          #   | 32 MiB for FIT image
                          #   v
  Kernel load address:    #  0xC4000000
                          #   |
                          #   | 32 MiB for Kernel
                          #   v
  DTB/DTBO load address:  #  0xC6000000
                          #   |
                          #   | Size for DTB/DTBO
                          #   v

Total memory mapped: 96 MiB
