qcacmn: Unify radar simulation commands

Browse Source 
Replace all three radar simulation commands with a single variant which
will perform required functionality based on its number of arguments.

Existing variants of radar simulation commands:

    1). Bangradar:
          Description: Adds all subchannels of segment ID "0" in the
                       current channel to NOL.
          Syntax: radartool -i wifi0 bangradar.

    2). Second Segment Bangradar:
          Description: Adds all subchannels of segment ID "1" of the
                       current channel to NOL.
          Syntax: radartool -i wifi0 secondSegmentBangradar.

    3). Enhanced Bangradar:
          Description: Adds the radar infected subchannels computed based
                       on segment ID (X), chirp information (Y) and
                       frequency offset (Z) to NOL.
          Syntax: radartool -i wifi0 bangradarenh X Y Z.
                  where,
                    X - Segment ID.
                    Y - Is chirp/non chirp.
                    Z - Frequency offset.

New radar simulation command:
     Bangradar:
     Types of usage:
       1). No arguments:
           Description: Adds all subchannels in the current channel to NOL.
           Syntax: radartool -i wifi0 bangradar.

       2). 1 Argument:
           Description: Adds all subchannels of segment ID "X" of the
                        current channel to NOL.
           Syntax: radartool -i wifi0 bangradar X

       3). 3 Arguments:
           Description: Adds the radar infected subchannels computed based
                        on segment ID (X), chirp information (Y) and
                        frequency offset (Z) to NOL.
           Syntax: radartool -i wifi0 bangradar X Y Z
                  where,
                    X - Segment ID.
                    Y - Is chirp/non chirp.
                    Z - Frequency offset.

All other combinations of arguments will result in error (insufficient
arguments).
