Move the start of booting the DSP to earlier in the DAPM process, and
move the final starting of the DSP to later in the DAPM process. This
allows us to overlap some of the processing with other components of the
system being brought up.

Move the ADSP2 boot proceedure into a work structure in preparation for
running it asynchronously with the reset of the audio path bring up.

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.

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.

Now that we have regular register mapped controls we should be splitting
the control sets for ADSP1 and ADSP2 as the register maps are not
identical. Do that.

Older .bin files report the global coefficients as absolute address writes
to zero; maintain compatibility with them.

Sets the ADSP1 clock rate to match the system clock
rate. To support this the codec driver provides
details of register containing the system clock
control bits.

There are many firmwares available for ADSP devices. Add basic support
for selecting between them, including a couple of feature sets in the
set of available firmware to start off with.

WMDR coefficient files can specify coefficients in terms of algorithm
specific data regions. Record the start addresses of these regions while
parsing the algorithms and then use them to handle coefficients with
these formats.

Some ADSP devices can make use of DVFS to optimise power consumption
depending on the operating frequency of the DSP core. Implement
support for this in the generic ADSP code.

Many current Wolfson devices feature DSPs based around an architecture
known as ADSP.  Since there is a lot of commonality in the system
integration of these devices a common library will be used to provide
support for them.

This version provides equivalent support for ADSP1 to that currently
included in the WM2200 driver.
