The GPU code doesn't need to deal with the IOMMU directly, instead
it can all be hidden behind the etnaviv mmu interface. Move the
last remaining part into etnaviv mmu.

It is only relevant for the V1 MMU, so we should not do this in the
common code.

This function has external visibility and only handles the Vivant IOMMU
version 1. Rename to make this more clear and allow a clear separation
of the different IOMMU versions.
Also drop the domain parameter, as we can infer it from the GPU we are
dealing with.

Since d16e0faab91 (iommu: Allow selecting page sizes per domain) the
iommu core demands the page size to be set per domain, otherwise any
mapping attempts will be dropped. Make sure to set a valid page size
for the etnaviv iommu.

This adds the etnaviv DRM driver and hooks it up in Makefiles
and Kconfig.
