ASoC: dapm: Add a flag for not having widget name in kcontrol name 

The existing soc-dapm code may add a prefix to control names, which in
some cases is useful but in others leads to long and confusing kcontrol
names such as "gain 2.1 Main Playback Volume".

This patch suggests an added flag to prevent the widget name prefix
from being added. That flag will be set in the topology file on a
per-widget basis.

The flag no_wname_in_kcontrol_name is added to struct snd_soc_dapm_widget,
and the logic in dapm_create_or_share_kcontrol() is changed to not to
add widget name if the flag is set.
