This commit moves the registration of the mv88e6123_61_65, mv88e6131,
mv88e6171, mv88e6352 drivers from the generic mv88e6xxx driver to their
own modules.
It also removes the NET_DSA_MV88E6XXX Kconfig entry and the mv88e6xxx
module, and exports its symbols, since it is just meant to share common
code, and does not have to be a module.
This allows the switch drivers to be complete modules, remove the need
to expose the dsa_switch_driver structures, and reduce code.
