hal: add support for FFV get params
-Audio HAL to support FFV get_paramters via sound trigger
callback.
-FFV needs clients to pass down the SM handle info to get a few
paramerters with respect to the given SM handle but standard
get_parameters doesn't support kvpairs for input keys, it does
support for return of kvpairs, add support for a new delimiter
which will be used while sending keys in get_parameter.
-Enable Keep alive for Red Dragon
-Adjust volume gains based on the systems team tuned values
