New pdev paramters have been added to firmware 10.2,
hence update wmi interfaces to sync with.

Introduce a new wmi interface controls noise floor (NF) calibration
period via debugfs as firmware has introduced it on v10.2.
It allows users to modify frequency of NF calibration in millisecond
and changes RSSI reporting frequency consequently.
Short calibration period will trigger more frequent NF calibration,
so that RSSI reported in receive frames is more realistic.
Till now calibration was done at 30 seconds.

This doesn't handle firmware retstarts in any way, let me send v2 to fix
that.
