DMA zone on highbank should only be enabled for LPAE, but other platforms
can cause DMA zone to be selected resulting in this warning:
arch/arm/mach-highbank/highbank.c:180:2: warning: large integer implicitly truncated to unsigned type [-Woverflow]
Fix this by making dma_zone_size setting also depend on CONFIG_ARM_LPAE.
