soundwire: generic_bandwidth_allocation: add lane in sdw_group_params

All active streams with the same parameters are grouped together and the
params are stored in the sdw_group struct. We compute the required
bandwidth for each group. However, each lane has individual bandwidth.
Therefore, we should separate different lanes in different params groups.
Add lane variable to separate params groups.
