Danilo Krummrich 8ea0b6d5be rust: pci: make Bar lifetime-parameterized 
Convert pci::Bar<SIZE> to pci::Bar<'a, SIZE>, storing &'a Device<Bound>
to tie the BAR mapping lifetime to the device.

iomap_region_sized() now returns Result<Bar<'a, SIZE>> directly instead
of impl PinInit<Devres<Bar<SIZE>>, Error>.

Since the lifetime ties the mapping to the device's bound state, callers
no longer need Devres for the common case where the Bar lives in the
driver's private data.

Add Bar::into_devres() to consume the bar and register it as a
device-managed resource, returning Devres<Bar<'static, SIZE>>. The
lifetime is erased to 'static because Devres guarantees the bar does not
actually outlive the device -- access is revoked on unbind.
