ASoC: SOF: debug: Handle cases when fw_lib_prefix is not set, NULL

Browse Source 
The firmware libraries are not supported by IPC3, the fw_lib_path is not
a valid parameter and it is always NULL.
Do not create the debugfs file for IPC3 at all as it is not applicable.

With IPC4 some vendors/platforms might not support loadable libraries and
the fw_lib_prefix is left to NULL to indicate this.
Handle such case with allocating "Not supported" string.
