Subject[PATCH 01/04] iommu/ipmmu-vmsa: 32-bit ARM may have CONFIG_IOMMU_DMA=y
From: Magnus Damm <damm+renesas@opensource.se>

Instead of assuming that CONFIG_ARM=y also means CONFIG_IOMMU_DMA=n,
convert the #ifdefs to take CONFIG_IOMMU_DMA into consideration
so 32-bit ARM can make use of CONFIG_IOMMU_DMA=y as well once those
bits are in place.
