This can be useful in cases where e.g. an AP is running on one radio, and triggering a scan on another radio should not disturb it. Changing the allowed radios list for a vif is supported, but only while it is down. While it is possible to achieve the same by always explicitly specifying a frequency list for scan requests and ensuring that the wrong channel/band is never accidentally set on an unrelated interface, this change makes multi-radio wiphy setups a lot easier to deal with for CLI users. By itself, this patch only enforces the radio mask for scanning requests and remain-on-channel. Follow-up changes build on this to limit configured frequencies.

To meet this expectation, some drivers may need to group multiple discrete hardware each acting as a link in MLO under single wiphy. With this change, supported frequencies and interface combinations of each individual radio are reported to user space. This allows user space to figure out the limitations of what combination of channels can be used concurrently. Even for non-MLO devices, this improves support for devices capable of running on multiple channels at the same time.
