Subject: [PATCH AUTOSEL 4.9 03/62] Bluetooth: h5: Fix missing dependency on
 BT_HCIUART_SERDEV

[ Upstream commit 6c3711ec64fd23a9abc8aaf59a9429569a6282df ]

This driver was recently updated to use serdev, so add the appropriate

CONFIG_SERIAL_DEV_BUS is not enabled:

  CC [M]  drivers/bluetooth/hci_h5.o
drivers/bluetooth/hci_h5.c:934:36: warning: ‘h5_serdev_driver’ defined but not used [-Wunused-variable]
 static struct serdev_device_driver h5_serdev_driver = {
                                    ^~~~~~~~~~~~~~~~
