ASoC: core: add SOC_DOUBLE_RANGE_TLV() helper macro
No macro currently allows handling a stereo control that has left and right
in the same register and whose minimum register value is not zero. Add one
that does that.
Note that even though the snd_soc_*_volsw_range() look more appropriate
given the _range suffix, they are not suitable because they don't honor the
two shift values. The snd_soc_*_volsw() look more generic and are suitable
for the task.
