Bug description:
[Impact]
When we boot the kernel on a Dell machchine which has a discrete
nvidia graphic card, the sof driver will fail to initialize sometimes,
and after investigation, we found if let nvidia hdmi audio load the
codec driver first, the sof driver will fail to initialize 100%.
[Fix]
Intel release a patch to fix this issue, after applying this patch,
the sof driver could work even the nividia hdmi audio initializes
first.
[Test Case]
We test this patch, the issue could be reproduced anymore in
100 times reboot.
[Regression Risk]
Low, Intel released the patch to us, and we already did large
numbers of audio test in the oem project.
