That's actually not what happens. You only need to call it for those
boards that need to load a HDA "VERB table". Many boards should be able
to work without loading a VERB. Unfortuntately I could not test this on
all MCP55 boards, so hence the "safe way".

Providing the HDA VERB table is a mainboard specific thing. So it
belongs into the mainboard.

We could add some magic to load the VERB upon CONFIG_LOAD_VERB. I
considered this back when I implemented the algorithm, but it would even
more mean jumping between components with the code and making it harder
to understand.

In which way?
