iommu/arm-smmu: Avoid build warning
ARM allmodconfig gained a new warning when dma_addr_t is 32-bit wide:
drivers/iommu/arm-smmu.c: In function 'arm_smmu_iova_to_phys_hard':
drivers/iommu/arm-smmu.c:1255:3: warning: right shift count >= width of type
This changes the calculation so that the effective type is always
64-bit.
