Danilo Krummrich 89f55d04c6 rust: io: make IoMem and ExclusiveIoMem lifetime-parameterized ...

Add a lifetime parameter to IoMem<'a, SIZE> and ExclusiveIoMem<'a,
SIZE>, storing a &'a Device<Bound> reference to tie the mapping to the
device's lifetime.

This mirrors the pci::Bar<'a, SIZE> design and enables drivers to hold
I/O memory mappings directly in their HRT private data, tied to the
device lifetime.

IoRequest::iomap_* methods now return the mapping directly instead of
wrapping it in Devres. Callers that need device-managed revocation can
call the new into_devres() method.
