net: dsa: Relocate master ethtool operations

Browse Source 
Relocate master_ethtool_ops and master_orig_ethtool_ops into struct
dsa_port in order to be both consistent, and make things self contained
within the dsa_port structure.

This is a preliminary change to supporting multiple CPU port interfaces.
