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: 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.
