ALSA: hda: cs35l41: Remove unnecessary boolean state variable firmware_running

This state duplicates the running state inside cs_dsp, so is not necessary.
Remove it, and use cs_dsp.running instead.
This brings the CS35L41 HDA driver more inline with its ASoC version,
allowing the same state to be used when calling library functions.
