[GIT PULL] iommu/arm-smmu: Updates for 6.12

[Will Deacon]

Hi Joerg,

Please pull these Arm SMMU updates for v6.12. The big new feature is
support for NVIDIA's virtual command queue implementation for SMMUv3,
but everything is summarised in the tag.

** Please note **: I've already pushed this to the arm/smmu branch for
-next coverage, but I thought sending a pull request was still useful
for the records and the signed tag. If you want to recreate the branch,
please feel free.

See you at LPC!

Cheers,

Will

----------------------------------------------------------------
Arm SMMU updates for 6.12

- SMMUv2:
  * Devicetree binding updates for Qualcomm MMU-500 implementations.
  * Extend workarounds for broken Qualcomm hypervisor to avoid touching
    features that are not available (e.g. 16KiB page support, reserved
    context banks).

- SMMUv3:
  * Support for NVIDIA's custom virtual command queue hardware.
  * Fix Stage-2 stall configuration and extend tests to cover this area.
  * A bunch of driver cleanups, including simplification of the master
    rbtree code.

- Plus minor cleanups and fixes across both drivers.
