chrontel: add a thread to report hdmi audio availability to cras.
There was a race that if chrontel reports the hdmi audio state before
cras is ready to accept it, the state is lost. Now we will retry after
five seconds.
BUG=chromium:257099
TEST=plug hdmi cable, boot zgb, verify audio goes to hdmi monitor.
