dma-iommu: Fix compilation when !CONFIG_IOMMU_DMA

Inclusion of include/dma-iommu.h when CONFIG_IOMMU_DMA is not selected
results in the following splat:

In file included from drivers/irqchip/irq-gic-v3-mbi.c:20:0:
./include/linux/dma-iommu.h:95:69: error: unknown type name âdma_addr_tâ
 static inline int iommu_get_msi_cookie(struct iommu_domain *domain, dma_addr_t base)
                                                                     ^~~~~~~~~~

                                                                          ^~~~~~~~~
scripts/Makefile.build:312: recipe for target 'drivers/irqchip/irq-gic-v3-mbi.o' failed

Fix it by including linux/types.h.
