Bug description:
Please apply the fix for #1872569 first, then apply this patch.

[Impact]
The fix for #1872569 introduces a regression, the driver access a
NULL pointer on the machiens without Intel hdmi audio codec.

[Fix]
pick a fixing patch from alsa/asoc repo, the patch doesn't assume
the first rtd is for hda codec, it will look for that rtd through
strstr()

[Test Case]
Boot the kenrel on those 2 Dell and 2 Lenovo machines which uses
this driver, the audio could work. disable the intel hdmi audio codec
through bios, the analogue audio still works


[Regression Risk]
Low, I have tested this patch Lenovo / Dell machines, they all worked well.
