Subject: [PATCH 16/18] ALSA: hda: cs35l56: Fix filename string field layout

Change the filename field layout to:
  cs35l56-rev[-s]-dsp1-misc[-sub].[wmfw|bin]

This is to keep the same firmware file naming scheme as the
CS35L56 ASoC driver.

This is not a compatibility break because no firmware files have
been published.

The original field layout matched the ASoC driver, but the way the
ASoC driver used the wm_adsp driver config to form this filename
was bugged. Fixing the ASoC driver to use the correct wm_adsp config
strings means that the 's' flag (to indicate a secured part) has to
move to somewhere after the first '-'.
