To repeat what's been said before if you are implementing register I/O
you *MUST* use regmap to do this.  What's not been clear is if this
device has a control interface that looks enough like a register map to
be implemented like one but since we're just guessing based on a
combination of the code and the HDA spec it's not entirely clear.
