intel_sst: MRST can only do mono recording
Fix bug
$ arecord -Dplughw -c2
Recording WAVE 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Stereo
arecord: set_params:1116: Unable to install hw params:
ACCESS: RW_INTERLEAVED
FORMAT: U8
SUBFORMAT: STD
SAMPLE_BITS: 8
FRAME_BITS: 16
CHANNELS: 2
[...]
Root cause is, the driver is reporting 2-channel capture capability
that is not supported by the MRST hardware. So the plughw plugin
end up requesting 2-channel capture which fails.
