Fix the dma-range size when the DT attribute is missing, i.e., set size to
dev->coherent_dma_mask + 1 instead of dev->coherent_dma_mask. Also add
code to check invalid values of size configured in DT and log error.

Limit the dma_mask to minimum of dma_mask and dma_base + size - 1.
Also arm_iommu_create_mapping() has size parameter of size_t and
arm_setup_iommu_dma_ops() can take a value higher than that. So
limit the size to SIZE_MAX.
