[GIT PULL] iommu/arm-smmu: First batch of updates for 5.11

[Will Deacon]

Hi Joerg,

Please can you pull these Arm SMMU updates for 5.11 so that they can get
into -next? I think Bjorn is keen to get a bunch of DT updates moving, so
the sooner we can get this lot out there, the better. Summary in the tag.

There are a few other patches kicking around on the list, so I may send
a second pull on top in a couple of weeks or so.

Cheers,

Will
