When SERDEV is a loadable module, and the HCI code is built-in, we
get a link error:

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.
