ALSA: hda: cs35l56: Fix order of searching for firmware files

Check for the cases of system-specific bin file without a
wmfw before falling back to looking for a generic wmfw.

All system-specific options should be tried before falling
back to loading a generic wmfw/bin. With the original code,
the presence of a fallback generic wmfw on the filesystem
would prevent using a system-specific tuning with a ROM
firmware.
