At the moment we only support ACPI enumeration for serial port attached

This commit adds a dependency on ACPI to the BT_HCIUART_RTL configuration
option, fixing the following warning when ACPI is not enabled:

I wonder whether CONFIG_BT_HCIUART_3WIRE should also
depend on ACPI and/or become a silent option, since it's currently
useless when either ACPI or BT_HCIUART_RTL are disabled,
and it seems possible that things break differently when another
back-end gets added there.
