Subject: qtnfmac: include full channels info to regulatory notifier

Before regulatory notifier is invoked by a wireless core, it will
update band information for the wiphy. Pass this information to
firmware together with new region alpha2 code.

Subject: qtnfmac: allow each MAC to specify its own regulatory rules

Currently driver uses the same regulatory rules to register all wiphy
instances. This is not logically correct since each wiphy may have
different capabilities (different supported bands, EIRP etc).
Allow firmware to pass regulatory rules for each MAC separately.

Subject: qtnfmac: use scan duration param for different scan types

Use scan duration param for both active and passive scan dwell times.
Document what different types of dwell times are used for. Explicitly
specify that if unset, automatic selection by device firmware
will be used.

Subject: qtnfmac: allow to control DFS slave radar detection

In ETSI region DFS slave device can operate in two modes on DFS channels:
 - do on-channel radar detection and use higher Tx power
 - don't do radar detection and use lower Tx power as a consequence

Allow user to control that behavior through qtnfmac module parameter.
