IOMMU Updates for Linux v6.15

Including:

- Core: IOMMUFD dependencies from Jason:
- Change the iommufd fault handle into an always present hwpt handle in
the domain
- Give iommufd its own SW_MSI implementation along with some IRQ layer
rework
- Improvements to the handle attach API

- Core: Fixes for probe-issues from Robin

- Intel VT-d changes:
- Checking for SVA support in domain allocation and attach paths
- Move PCI ATS and PRI configuration into probe paths
- Fix a pentential hang on reboot -f
- Miscellaneous cleanups

- AMD-Vi changes:
- Support for up to 2k IRQs per PCI device function
- Set of smaller fixes

- ARM-SMMU changes:
- SMMUv2 devicetree binding updates for Qualcomm implementations
(QCS8300 GPU and MSM8937)
- Clean up SMMUv2 runtime PM implementation to help with wider rework of
pm_runtime_put_autosuspend()

- Rockchip driver changes:
- Driver adjustments for recent DT probing changes

- S390 IOMMU changes:
- Support for IOMMU passthrough

- Apple Dart changes:
- Driver adjustments to meet ISP device requirements
- Null-ptr deref fix
- Disable subpage protection for DART 1
