asoc: msm-lsm-client: add support for ADSP Generic Detection Event
ADSP detection engine module can raise Generic Detection Event to provide variable payload data based on the information requested by userspace. Adding new API/interface to provide support for Generic Detection Event in LSM drivers. Change-Id: Id5541f959ecdcf862dcfa1de1c1a1b3a796f260c Signed-off-by: Xiaoyu Ye <benyxy@codeaurora.org>
