ASoC: skip the endpoint that doesn't present and

Merge series from Bard Liao <yung-chuan.liao@linux.intel.com>:

A codec endpoint may not be used. We could check the present SDCA
functions to know if the endpoint is used or not. Skip the endpoint
which is not used. And load the topology dynamically for each endpoint.
With this feature, we don't need to use the quirk to determine the
existence of the optional codec DAIs.
