some ubuntu eoan/bionic users reported that the audio driver failed
to initialize, then the audio didn't work. I checked the dmesg, found
the sof driver planed to load sof-cfl.ri, but there is no this
firmware under eoan or bionic.

I consulted with Intel audio team, they told me that the coffeelake
platform could share the firmware with cnl/whl platoforms, so we could
build a symbol link sof-cfl->sof-cnl.

[Test Case]
A couple of ubuntu users already tested it on Dell and Asus coffeelake
laptops, it worked well.

[Regression Risk]
Low, users already tested it, and Intel audio team confirmed it is safe.
