It is no longer possible to build BT_HCIUART into the kernel when SERIAL_DEV_BUS is a loadable module, even if none of the SERIAL_DEV_BUS based implementations are selected:
drivers/bluetooth/hci_ldisc.o: In function `hci_uart_set_flow_control': hci_ldisc.c:(.text+0xb40): undefined reference to `serdev_device_set_flow_control' hci_ldisc.c:(.text+0xb5c): undefined reference to `serdev_device_set_tiocm'
This adds a dependency to avoid the broken configuration.
