Add stream token SOF_TKN_STREAM_PLAYBACK_COMPATIBLE_D0I3 and
SOF_TKN_STREAM_CAPTURE_COMPATIBLE_D0I3 to denote if the stream can be
opened at low power d0i3 status or not.

By any chance, can stream be playback D0ix incompatible but capture D0ix compatible? Single token would suffice, no?

we discussed this on github. If we generalize this to low-power streaming, it's possible to have a case where the buffering is not suitable on capture but suitable on playback, or vice-versa, so we added two tokens.
