[PATCH] ASoC: Fix long name of control for dapm_switch

[Joonyoung Shim <dofmind@gmail.com>]

The length of long control name doesn't include the length of widget
name at present when widget->id is snd_soc_dapm_switch, so the long
control name of dapm_switch is shortened.
To avoid this problem, the long control name only for dapm_mixer_named_ctl
must have simply the kcontrol name.
