scsi: ufs: Remove stringize operator '#' restriction
Current EM macro definition, we use stringize operator '#', which turns the argument it precedes into a quoted string. Thus requires the symbol of __print_symbolic() should be the string corresponding to the name of the enum. However, we have other cases, the symbol and enum name are not the same, we can redefine EM/EMe, but there will introduce some redundant codes. This patch is to remove this restriction, let others reuse the current EM/EMe definition.
