[PATCH] iommu/arm-smmu: Fix build issues

[Robin Murphy]

In a hurry to get things ready for merging, we missed that one more
include needs moving to arm-smmu.h along with the register accessors
to prevent 32-bit builds breaking, and some missing static specifiers
made Sparse sad.

I already fixed the static stuff locally (and I think you missed
'calxeda_impl'), so I'll reword this and just take the missing include.

Thanks,
