ARM: mvebu: switch the Armada XP DB to use internal registers at 0xf1000000
Marvell has now provided bootloaders that are Device Tree capable for the Armada XP DB board, and that also remap the internal register base address to 0xf1000000. In addition, the bootloader now sets the MBus Window base address to 0xf0000000, but on this board, this change doesn't make much difference since the board is by default equipped with 2 GB of RAM. Therefore this commit updates the soc->ranges Device Tree property with the fact that the internal registers are now mapped at 0xf1000000.
