ASoC: ops: Remove snd_soc_info_volsw_range()

The only difference between snd_soc_info_volsw() and
snd_soc_info_volsw_range() is that the later will not force a 2
value control to be of type integer if the name ends in "Volume".

The kernel currently contains no users of snd_soc_info_volsw_range()
that would return a boolean control with this code, so the risk is
quite low and it seems appropriate that it should contain volume
control detection. So remove snd_soc_info_volsw_range() and point its
users at snd_soc_info_volsw().
