net: dsa: use dsa_tree_for_each_cpu_port in dsa_tree_{setup,teardown}_master
More logic will be added to dsa_tree_setup_master() and
dsa_tree_teardown_master() in upcoming changes.
Reduce the indentation by one level in these functions by introducing
and using a dedicated iterator for CPU ports of a tree.
