Currently a device which has a DFS channel selected using the UCI
channel setting might switch to a non-DFS channel in case no chanlist is
provided (UCI setting "channels") when the radio detects a DFS event.

Automatically add a chanlist consisting of the configured channel when
the device does not operate in auto-channel mode and no chanlist set to
circumvent this issue.
