To be able to support different firmwares and tuning for different models, the driver needs to be able to load a different firmware and coefficient file based on its Subsystem ID.
The driver attempts to load the firmware in the following order:
/lib/firmware/cirrus/cs35l41-dsp1-<fw-type>-<ssid>-dev<#>.wmfw /lib/firmware/cirrus/cs35l41-dsp1-<fw-type>-<ssid>.wmfw /lib/firmware/cirrus/cs35l41-dsp1-<fw-type>.wmfw
