Clang warning:
>> sound/soc/intel/boards/sof_ssp_amp.c:97:6: warning: variable 'i'
   set but not used [-Wunused-but-set-variable]
           int i = 0;
               ^

The device counter is not used when the quirk is not set, which static
analysis cannot know. Move its initialization before the loop to
remove this warning.
