It is similar but sst_machines structure is entirely different. In Skylake
case we only need machine entry name and rest of the information is coming
from topology manifest data. I will try to move this as well to topology
data later, but for now on upstream to get audio out from boards I need this
patch :)

I am not sure I follow the comment on user, the SKL driver here is user in
this

as explained above code is similar but everyone uses different sst_machines
strcuture.
