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. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

ASoC: wm_adsp: Add basic support for rev 1 firmware file format Revision one of the file format includes new algorithm and coefficient blocks which provide additional information about the controls exported by the firmware. This patch updates the processing to handle this version of the file format. Note that whilst this version of the format adds support for specifying a name for the control through the firmware file this has not been used and to keep compatibility with existing deployments no changes to the firmware control naming are made by this patch.

ASoC: wm_adsp: Move DVFS control into codec driver In theory the ADSP driver should not need to know anything about the codec it is part of.

ASoC: wm_adsp: Improve variable naming We have wm_adsp_region, wm_adsp_alg_region, and wmfw_region, the variables for which are all frequently called region, this can get quite confusing when reviewing the code especially given some functions are quite long. Consistently use mem for wm_adsp_regions, alg_region for wm_adsp_alg_region and region for wmfw_region. Additionally, we use a mix of adsp and dsp for pointers to the wm_adsp structure standardise this on dsp. Finally, we use algs to refer to the number of algorithms quite frequently, change this to the more descriptive n_algs.
