msm-lsm-client: decouple input and output hardware parameters

With multichannel voice activation support in LSM, it could be possible
that the input media format/hw_params to LSM would be different than
the output media format/hw_params. This change decouples the input
and output hw_params for LSM. The output hw_params are obtained through
ALSA pcm_hw_params operation, whereas the input hw_params are obtained
though the LSM_SET_INPUT_HW_PARAMS ioctl to LSM.

At the same time, the below parameter IDs are added to send the channel
information to LSM service:
	- LSM_PARAM_ID_MEDIA_FMT_V2
	- LSM_PARAM_ID_LAB_OUTPUT_CHANNEL_CONFIG
