ARM: use ARM_DMA_ZONE_SIZE to adjust the zone sizes
Rather than each platform providing its own function to adjust the zone sizes, use the new ARM_DMA_ZONE_SIZE definition to perform this adjustment. This ensures that the actual DMA zone size and the ISA_DMA_THRESHOLD/MAX_DMA_ADDRESS definitions are consistent with each other, and moves this complexity out of the platform code.
