[GIT PULL] iommu/arm-smmu: Updates for 5.19

[Will Deacon]

Hi Joerg,

Please pull these Arm SMMU updates for 5.19. The bulk of it is just adding
new device-tree compatible strings for the existing drivers, but there
are some non-critical fixes in here as well. Please see the tag for more
details.

I used the previous fixes pull as a base for this so that you shouldn't
run into any conflicts with upstream.

Cheers,

Will
