iwlwifi: add function to reset/tune radio if needed
Adding "radio reset" function to help reset and stabilize the radio. During normal operation, sometime for unknown reason, radio encounter problem and can not recover by itself; the best way to recover from it is to reset and re-tune the radio. Currently, there is no RF reset command available, but since radio will get reset when switching channel, use internal hw scan request to force radio reset and get back to normal operation state. The internal hw scan will only perform passive scan on the first available channel (not the channel being used) in associated state. The request should be ignored if already performing scan operation or STA is not in associated state. Also include an "internal_scan" debugfs file to help trigger the internal scan from user mode.
