Danilo Krummrich bde0149ce5 rust: dma: tie DMA allocations to the device's bound lifetime
DMA allocations carry device resources (e.g. IOMMU mappings) that must
 not outlive the device's bound lifetime. Add lifetime parameters to the
 DMA allocation types (Coherent, CoherentBox, CoherentHandle) to enforce
 at compile time that they are freed before the device is unbound.
 
 Since DMA types with lifetime parameters are exposed through debugfs in
 the nova-core driver, first drop the unnecessary T: 'static bound from
 the debugfs ScopedDir file creation methods by formalizing a type
 invariant on FileOps.
 
 This is a stable tag for other trees to merge.
