ac50009f64 ASoC: wm_adsp: Add support for firmware wide coefficient blocks
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.

b6ed61cfa2 ASoC: wm_adsp: Split ADSP1 and ADSP2 firmware controls
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.

dc91428a61 ASoC: arizona: Basic support for ISRC rate selection
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.

f4b828128a ASoC: wm_adsp: fix possible memory leak in wm_adsp_load_coeff()
'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.

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.
