ALSA: hda: cs35l41: Fix comments wrt serial-multi-instantiate reference

The comments are inconsistent and point to the wrong driver name.
The initially named i2c-multi-instantiate it was renamed to the
serial-multi-instantiate exactly due to support of the platforms
with multiple CS35L41 codecs.

Fix comments accordingly.

While at it, drop file names from the files.
