alsa-ucm: Let profiles know their associated UCM verb

Browse source 
Currently each UCM verb generates one profile named the same as the
verb, meaning it's trivial to know which verb the profile belongs to.
This will be slightly harder to do when we generate multiple profiles
per UCM verb (e.g. to make use of conflicting devices).

It would still be possible to parse the profile name to get the UCM
verb, but instead let's keep track of the struct instance representing
the profile's associated verb. This also lets us remove a block of code
searching for the verb by its name.

[Alper: Reused Jaroslav's UCM profile context changes for UCM verb
instead of combined devices.]
