[PATCH] ASoC: audio-graph-card: Drop remote-endpoint as required property

[Sameer Pujar]

Hi Rob,

>>> The remote-endpoint may not be available if it is part of some
>>> pluggable module. One such example would be an audio card, the
>>> Codec endpoint will not be available until it is plugged in.
>>> Hence drop 'remote-endpoint' as a required property.
>> Please hold off on this. I have more changes coming.

Is this a good time to push for audio-graph-port changes?
