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.

Firmwares may provide some firmware wide configuration regions which can
be configured by the coefficient files using the firmware ID as the
algorithm ID, include these in the algorithm list.

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.

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.

'file' is malloced in wm_adsp_load_coeff() and should be freed
before leaving from the error handling cases, otherwise it will cause
memory leak.

Normally kmalloc() returns things that are DMA safe so not visible on all
platforms but we do need to explicitly request DMA safe memory.

Implement support for a new revision of the coefficeint file format for
ADSP cores.
Since coefficient file format 0 has not been widely deployed and is very
unlikely to ever be used with this driver code support for it has been
removed.

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.
