net: dsa: mv88e6xxx: Add devlink regions
Allow the global registers, and the ATU to be snapshot via devlink
regions. It is later planned to add support for the port registers.
v2:
Remove left over debug prints
Comment ATU format is generic for mv88e6xxx, not wider
v3:
Make use of ops structure passed to snapshot function
Remove port regions
v4:
Make use of enum mv88e6xxx_region_id
Fix global2/global1 read typ0
