Stefan Binding d04ce4113c ALSA: cs35l41: Fix for old systems which do not support command 
Some older laptops using cs35l41 use firmware which does not support
the CSPL_MBOX_CMD_SPK_OUT_ENABLE command.
Firmware versions v0.28.0 and older do not support this command.

Fixes: fa3efcc36a ("ALSA: cs35l41: Use mbox command to enable speaker output for external boost")
