hal: retrieve license info during init.

FFV/Allplay requires licensing info during init.
 - Retrieve Product_Id using "meta_info_key" from platfrom xml file during HAL-Init.
 - Retrieve Product_License using "audio_calibration_info" from ACDB.
 - Extend QAHW GetParam API to access AllPlay License information.
