Commit 2d5a5612bc (arm64: Limit the CMA buffer to 32-bit if ZONE_DMA)
forces the CMA buffer to be 32-bit addressable if CONFIG_ZONE_DMA is
defined. This breaks CMA on platforms with no 32-bit addressable DRAM.
This patch checks to make sure there is 32-bit addressable DRAM before
setting the 32-bit
