When SERDEV is a loadable module, and the HCI code is built-in, we
get a link error:
drivers/bluetooth/built-in.o: In function `ll_close':
hci_ll.c:(.text+0x278d): undefined reference to `serdev_device_close'
drivers/bluetooth/built-in.o: In function `hci_ti_probe':
hci_ll.c:(.text+0x283c): undefined reference to `hci_uart_register_device'
drivers/bluetooth/built-in.o: In function `ll_setup':
hci_ll.c:(.text+0x289e): undefined reference to `serdev_device_set_flow_control'
hci_ll.c:(.text+0x2b9c): undefined reference to `serdev_device_set_baudrate'
drivers/bluetooth/built-in.o: In function `ll_open':

drivers/bluetooth/built-in.o: In function `ll_init':
(.init.text+0x10d): undefined reference to `__serdev_device_driver_register'
We already have CONFIG_BT_HCIUART_SERDEV as a Kconfig symbol that is
set when the serdev code is reachable by a driver. Unlike the nokia
driver, this one can also be built when serdev is completely disabled,
so we add a dependency on serdev either being usable or disabled here.

I thought this was okay because of the differences with the nokia
driver, but I should have tested it. In hindsight, serdev as a module
is really a PIA considering that it effectively has to be built-in due
to TTY dependencies.

this does not apply against bluetooth-next tree. Can you respin it with the acks.
