[Remove Mbox3 UCM] Request to revert pull 237

alsa-project/alsa-ucm-conf issue #412 was opened from ManuLinares:

https://github.com/alsa-project/alsa-ucm-conf/pull/237

The SplitPCM adds not only latency, https://github.com/alsa-project/alsa-ucm-conf/issues/238 but other general issues when streaming, etc.

So I propose removing the UCM profile.
