[GIT PULL] iommu/arm-smmu: Updates for 5.14

[Will Deacon <will@kernel.org>]

Hi Joerg,

Please pull these Arm SMMU updates for 5.14.

Of particular note is the support for stalling faults with platform devices
using SMMUv3 -- this concludes the bulk of the SVA work from Jean-Philippe.

Other than that, one thing to note is that the patch from Thierry adding
the '->prove_finalize' implementation hook is also shared with the
memory-controller tree, since they build on top of it to get the SMMU
working with an nvidia SOC. Unfortunately, that patch also caused a NULL
dereference on other parts, so there's a subsequent patch on top here
addressing that.

Due to the above, the sooner this lands in -next, the better.

Cheers,

Will
