net: dsa: mv88e6xxx: Give each hw stat an ID

Browse Source 
With the upcoming standard counter group support, we are no longer
reading out the whole set of counters, but rather mapping a subset to
the requested group.

Therefore, create an enum with an ID for each stat, such that
mv88e6xxx_hw_stats[] can be subscripted with a human-readable ID
corresponding to the counter's name.
