ASoC: wm_adsp: Convert '/' to '-' when normalizing firmware filenames

Browse source

Don't preserve '/' in firmware filename fields - convert it to '-' like
other punctuation characters.

The code originally normalized the entire string, including the
directory prefix. To prevent breaking the directory it had to preserve
'/' characters in the name, but this meant that the system name and ALSA
prefix must not contain those characters.

It's trivial to skip the directory name prefix and start the
normalization after it, and that means the normalization does not need
to make a special case for '/'.
