Subject: mlxsw: spectrum: push cls_flower and cls_matchall setup_tc processing
 into separate functions
Patch-mainline: v4.14-rc1
Git-commit: fd33f1dfed6141280bc85817e6f79b87a5c7320b
References: bsc#1056787

Let mlxsw_sp_setup_tc be a splitter for specific setup_tc types and push
out cls_flower and cls_matchall specific codes into separate functions.
