Subject: [v2] ASoC: bt-sco: fix bt-sco-pcm-wb dai widget don't connect to the endpoint

This patch fix the second dai driver's dai widget can't connect to the
endpoint. Because "bt-sco-pcm" and "bt-sco-pcm-wb" dai driver have the
same stream_name, so it will cause they have the same widget name.
Therefor it will just create only one route when do snd_soc_dapm_add_route
that only find the widget through the widget name.

Change from v1:
   fix build error

Hi maintainer,
   Need your comments. The patch is the one that I think it makes the
   most sense. Maybe we can define the new stream_name for
   "bt-sco-pcm-wb" and add the new route.
