Vignesh Mohan 2b0ff06748 qcacmn: Add support for Bangradar with detector ID 
Provide support for bangradar with detector ID as one of the parameters.
Add the parameter as part of the packed arguments to be sent to FW.

Also add APIs for basic sanity check of bangradar params and packing
bangradar params inside an 32 bit unsigned integer.
