Add capture stream to CPU_I2S_ENCODER. This is the final step to add
support for I2S capture following the recent addition of
"audin-decoder-i2s" and "audin-fifo".

As for the naming of the stream "I2S Encoder" is kept as base following
the same pattern used for the playback stream and with the goal to minimize
changes.
