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.
