PD#149114: S420 V03 speaker no sound when playing 2-ch wav

S400 & S420 modify the lineout and speaker out on TDMC dataIO2.
This commit make the speaker output available
by the output lanemask setting:

    "dai-tdm-lane-slot-mask-out = <0 0 1 0>;"

It masks the third lane as data output when playing two channel
PCM waves.
