ASoC: ops: Fix boolean/integer detection for simple controls

The standard snd_soc_info_volsw() detects if a control is a volume control
and needs to be reported as an integer even if it only has two values by
looking for the string " Volume" in the control name. This results in false
positives if the control has a name like "HP Volume Ramp Switch" since any
" Volume" is matched, not just a trailing one. Fix this by making sure that
we only match at the end of the control name.
