Audio: fix no sound for switching mat to pcm [1/1]

Browse Source 
PD#SWPL-176561
PD#OTT-61559

Problem:
switch to pcm from auto,sometimes no sound.

Solution:
HDMITX not prepare/reset fifo/buffer for
this switching action, some sink device can‘t
parse these data that causes no sound.

Audio invoke callback to inform hdmitx prepare
for this case. That can resolve this issue.

Verify:
local coffey + S7D
