Having the tag protocol in dsa_switch_driver for setup time and in
dsa_switch_tree for runtime is enough. Remove dsa_switch's one.

I had to think about this one for a minute. At the moment it is good,
however, sometime in the future, we might want to revert it. Some
Marvell switches support two tagging schemes. At the moment, we have
no way to express that, so the switch driver only offers one. If we
were to extend the API to express a list of supported tagging schemes,
we would then want dsa_switch to contain the scheme actually chosen.
However, until we actually implement something like this, lets remove
it.

Applied.
