IOMMU Updates for Linux v6.14

Including:

	- Core changes:
	  - PASID support for the blocked_domain.

	- ARM-SMMU Updates:
	  - SMMUv2:
	    * Implement per-client prefetcher configuration on Qualcomm SoCs.
	    * Support for the Adreno SMMU on Qualcomm's SDM670 SOC.
	  - SMMUv3:
	    * Pretty-printing of event records.
	    * Drop the ->domain_alloc_paging implementation in favour of
	      ->domain_alloc_paging_flags(flags==0).
	  - IO-PGTable:
	    * Generalisation of the page-table walker to enable external walkers
	      (e.g. for debugging unexpected page-faults from the GPU).
	    * Minor fix for handling concatenated PGDs at stage-2 with 16KiB pages.
	  - Misc:
	    * Clean-up device probing and replace the crufty probe-deferral hack
	      with a more robust implementation of arm_smmu_get_by_fwnode().
	    * Device-tree binding updates for a bunch of Qualcomm platforms.

	- Intel VT-d Updates:
	  - Remove domain_alloc_paging().
	  - Remove capability audit code.
	  - Draining PRQ in sva unbind path when FPD bit set.
	  - Link cache tags of same iommu unit together.

	- AMD-Vi Updates:
	  - Use CMPXCHG128 to update DTE.
	  - Cleanups of the domain_alloc_paging() path.

	- RiscV IOMMU:
	  - Platform MSI support.
	  - Shutdown support.

	- Rockchip IOMMU:
	  - Add DT bindings for Rockchip RK3576.

	- More smaller fixes and cleanups.
