Deborah Brouwer 233f147985 rust: iommu: add device lifetime to IoPageTable ... Currently, using a raw IoPageTable is unsafe because the returned IoPageTable is not tied to the device driver binding lifetime. Since device drivers now receive a lifetime parameter <'bound> representing the interval during which a device driver is bound to its bus device, add a lifetime parameter to IoPageTable. This ensures that the returned IoPageTable cannot outlive the bus device binding. Also remove the option to create a page table as a device resource since currently Devres is not compatible with resources that have a lifetime parameter. This option can be restored once the lifetime-aware wrapper for devres is available and if a use-case appears for it.
