Still WIP. I want to add at least names for the global1 and glabel2.

This is all specific to the mv88e6xxx. Vivien had two debugfs
patchsets. One for generic DSA properties and a second one for
mv88e6xxx specific stuff. The regions i've added only cover the
mv88e6xxx specific stuff.
The recent devlink metric's should help with some parts of the generic
debugfs code.
