No need to hold on to the `codec' pointer.  We can use the `dsp'
pointer and grab all the information we need from there.  This
makes the parameters for the functions a bit more sane and idiomatic.

Get rid off the wm_coeff struct and the wm_coeff_add_kcontrol()
function.  We are now using the snd_soc_card_kcontrol() function to
get the kcontrol pointers.  No need to call into ALSA code to
register the kcontrols.

Rename `dirty' to `set' as it is a bit more descriptive.  A set
control is any control that has been set by the user.  We need to ensure
that everytime we boot the DSP we sync out any controls that were
set.

We could at some point start keeping track of the default values of
the controls to suppress some of the device I/O.

Add initial support for runtime tuning for the ADSP cores.  This
is achieved by exposing the coefficient configuration blocks as
ALSA binary controls.
The current code assumes that no controls on the DSP are volatile.

Since ASoC does not yet really have the framework features needed to
support propagating sample rates through the device well yet implement
basic support for the ISRCs equivalent to that we currently have for the
ASRCs. The user can opt for 8kHz or 16kHz as the rate for the DSP blocks
in addition to the main audio rate, these being the primary use cases.
