Danilo Krummrich bed87375f9 rust: dma: tie Coherent and CoherentBox to the device's bound lifetime 
Add a lifetime parameter to Coherent and CoherentBox that ties the DMA
allocation to the device's bound scope, ensuring it is freed before the
device is unbound.

DMA allocations carry device resources (e.g. IOMMU mappings) that must
not outlive the device's bound lifetime. Without a lifetime parameter,
there was no compile-time enforcement that a Coherent or CoherentBox is
dropped before the device is unbound.

Propagate the new lifetime parameter through all users.
