Convert some users of the MV88E6xxx DSA switch to module

Convert some users of the MV88E6xxx DSA switch to module

It is perfectly fine to load the MV88E6xxx DSA switch and
DSA tagger as modules.

Convert a few targets and their images to use this instead
of including MV88E6XXX into the kernel config. Kirkwood
and ixp4xx are already converted.

The two patches to mvebu and qoric can be applied separately,
they have no dependencies.
