1023dbd90c ASoC: wm_adsp: Add basic firmware selection support
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.

471f488583 ASoC: wm_adsp: Implement support for algorithm-specific coefficient blocks
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.

d62f4bc665 ASoC: wm_asdp: Validate sanity of algorithm count
If we run into I/O problems the algorithm count may be crazy, validate it
before we proceed and dump the read data for diagnostic purposes.

db40517c75 ASoC: wm_adsp: Add support for parsing algorithms
ADSP devices report information on the algorithms loaded on them.  Parse
this data and use it to allow coefficients to be configured for specific
algorithms.

a76fefab5c ASoC: wm_adsp: Ensure that block writes are from DMA aligned addresses
Otherwise we won't run correctly on systems that require this for larger
data transfers.

Turn off the ADSP memory when we aren't using it, saving a small amount of
power.

973838a030 ASoC: wm_adsp: Enable DVFS for ADSP2
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.

2159ad936b ASoC: adsp: Add ADSP base support
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.
