[ARM] Orion: DRAM mapping granularity is 64KiB, not 16MiB
The DRAM base address and size fields in the CPU's MBUS bridge have 64KiB granularity, instead of the currently used 16MiB. Since all of the currently supported MBUS peripherals support 64KiB granularity as well, this patch changes the Orion address map code to stop rounding base addresses down and sizes up to multiples of 16MiB.
