[PATCH v3 2/2] serdev: Update drivers/bluetooth/Kconfig for ACPI serdev support

[Ian W MORRISON <ianwmorrison-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

ACPI and DT both need SERIAL_DEV_CTRL_TTYPORT to work properly
since SERIAL_DEV_CTRL_TTYPORT is the only controller implemented for
serdev. This is only possible if serdev support is compiled in as the code
hooks into TTY. Otherwise PM will silently break as the corresponding
platform devices would no longer be registered and as the tty class
device is also gone and hciattach (btattach) will also fail.

This patch set addresses this by making BT_HCIUART_BCM dependent on
SERIAL_DEV_CTRL_TTYPORT which in turn is dependent on SERIAL_DEV_BUS
and ensures that if SERIAL_DEV_BUS is selected is the code is build it.
