Browse Source 
PD#SWPL-2491

Problem:
HDMI output no sound when system boot up

Solution:
When system bootup,there is no sound,Checked the issue, pcm_write always fail,
cat /d/aml_clkmsr/clkmsr ,[120][ 6000000]audio_spdifout_mst_clk.
the spdif has no clock.Seems after enable same source, the spdifa clock
is not configured correctly. now configure that to continous clock.
TBD, need check the root cause in alsa kernel code.

Verify:
verify by galilei, reboot 20 times.
