Subject: [PATCH net-next v2 03/18] net: dsa: mv88e6xxx: move VTU Operation accessors
Move the helper functions to access the Global 1 VTU Operation register
to a new global1_vtu.c file, and get rid of the old underscore prefix
naming convention. This file will be extended will all VTU/STU related
code.
