Subject: iommu/arm-smmu: Make private implementation details static
Git-commit: 4b67f1ddcf23d6dc4b5a3a486b758cb91f725e72
Patch-mainline: v5.4-rc1
References: bsc#1175713

Many of the device-specific implementation details in 'arm-smmu-impl.c'
are exposed to other compilation units. Whilst we may require this in
the future, let's make it all 'static' for now so that we can expose
things on a case-by-case basic.
