Merge branch 'dsa-mv88e6xxx-remove-Global-1-setup'

Vivien Didelot says:

====================
net: dsa: mv88e6xxx: remove Global 1 setup

The mv88e6xxx driver is still writing arbitrary registers at setup time,
e.g. priority override bits. Add ops for them and provide specific setup
functions for priority and stats before getting rid of the erroneous
mv88e6xxx_g1_setup code, as previously done with Global 2.
