ALSA: hda: cs35l41: Add initial DSP support and firmware loading
This patch adds support for the CS35L41 DSP.
The DSP allows for extra features, such as running
speaker protection algorithms and hibernations.
To utilize these features, the driver must load
firmware into the DSP, as well as various tuning
files which allow for customization for specific
models.
