Cc: Srinivasa Rao Mandadapu
Add four speaker support on MI2S secondary block
by using I2S SD1 line on gpio52 pin, and add channel map
control support in the lpass-cpu audio driver.
Signed-off-by: Srinivasa Rao Mandadapu <srivasam@codeaurora.org>

Changes Since V1:
-- removed set_channel_map/get_channel_map implementation as default kcontrols
added in pcm_new API.

AFAIU, You would need an empty entry at the end of this list if not we
will endup in a dereferencing memory sitting right next to this array
which will lead to random memory corruptions...
Have a look at some of the examples in existing codec drivers.
Other than that patch looks good.
