ASoC: ops: Remove snd_soc_get_volsw_range()

With the addition of the soc_mixer_reg_to_ctl() helper it is now very
clear that the only difference between snd_soc_get_volsw() and
snd_soc_get_volsw_range() is that the former supports double controls
with both values in the same register. As such we can combine both
functions.
