When a widget is added to dapm via snd_soc_dapm_new_widgets,
dapm_debugfs_add_widget is also called to create a corresponding debugfs
file. However, when a widget is freed by snd_soc_dapm_free_widget, the
corresponding debugfs is not cleared. As a result, the freed widget is
still seen in the dapm directory.

This patch adds dapm_debugfs_free_widget to free the debugfs of a
specified widget, and it's called at snd_soc_dapm_free_widget to clean
up the debugfs for freed widget.
