aw8695: Support repeatedly waveform playing

Browse source 
Play those waveforms repeatedly with wave id higher than 200;
Stop the repeatedly playing after 2 minutes automatically to avoid
the problem when no stop command is received as expected;

As for the Code-Review-1 of missing propagation to branch(es):
bq-shm2018

NO_PROP_NEEDED: This propagation is only needed when the change of
framework for this new feature is integrated, being done by engineers
in charge of that product.
