iommufd: Add IOMMU_HWPT_SET_DIRTY_TRACKING
Every IOMMU driver should be able to implement the needed iommu domain ops
to control dirty tracking.
Connect a hw_pagetable to the IOMMU core dirty tracking ops, specifically
the ability to enable/disable dirty tracking on an IOMMU domain
(hw_pagetable id). To that end add an io_pagetable kernel API to toggle
dirty tracking:
* iopt_set_dirty_tracking(iopt, [domain], state)
The intended caller of this is via the hw_pagetable object that is created.
Internally it will ensure the leftover dirty state is cleared /right
before/ dirty tracking starts. This is also useful for iommu drivers which
may decide that dirty tracking is always-enabled at boot without wanting to
toggle dynamically via corresponding iommu domain op.
