iommu: SUN50I_IOMMU should depend on HAS_DMA

Browse source 
If NO_DMA=y (e.g. Sun-3 all{mod,yes}-config):

    drivers/iommu/dma-iommu.o: In function `iommu_dma_mmap':
    dma-iommu.c:(.text+0x92e): undefined reference to `dma_pgprot'

IOMMU_DMA must not be selected, unless HAS_DMA=y.

Hence fix this by making SUN50I_IOMMU depend on HAS_DMA.
