BugLink: https://bugs.launchpad.net/bugs/2029199

To ensure firmware for cs35l41 is correctly running, it is necessary
that a corresponding tuning file is also loaded. Without both,
the firmware may not be performing correctly
Ensure that if we load the firmware, we have also loaded the correct
tuning file. Otherwise, fall back to default firmware and tuning.
If default tuning is also missing, then disable DSP firmware.
