Grzegorz Bernacki cfdb2eed92 Disable decoding windows with no FDT entry.
- On ARMADAXP B0 (GP development board) we are not able to use PCI due to
   whole 32-bit address space used by 4GB of RAM memory.
- Change is required to destroy unnecessary window to free address space
   for PCI and other devices
- Fix offset value for SDRAM decoding windows
