Bluetooth: hci_serdev: Move serdev_device_close/open into common hci_serdev code
Make hci_uart_register_device() and hci_uart_unregister_device() call serdev_device_close()/open() themselves instead of relying on the various hci_uart drivers to do this for them. Besides reducing code complexity, this also ensures correct error checking of serdev_device_open(), which was missing in a few drivers.
