ethtool: dsa: mv88e6xxx: add pretty dump

The mv88e6xxx DSA driver supports many Marvell devices all using 32
registers of 16 bits. However each devices have a slightly different
register definition.

This patch adds the boilerplate for providing an optional function
per mv88e6xxx switch. It does not pretty dump anything yet.
