ASoC: cs35l56: Fix misuse of wm_adsp 'part' string for silicon revision



Put the silicon revision and secured flag in the wm_adsp fwf_name
string instead of including them in the part string.

This changes the format of the firmware name string from

 cs35l56[s]-rev-misc[-system_name]

to
 cs35l56-rev[-s]-misc[-system_name]

No firmware files have been published, so this doesn't cause a
compatibility break.

Silicon revision and secured flag are included in the firmware
filename to pick a firmware compatible with the part. These strings
were being added to the part string, but that is a misuse of the
string. The correct place for these is the fwf_name string, which
is specifically intended to select between multiple firmware files
for the same part.

Backport note:
This won't apply to kernels older than v6.6.
