net: dsa: stop exposing tag proto module helpers to the world

The DSA tagging protocol driver macros are in the public include/net/dsa.h
probably because that's also where the DSA_TAG_PROTO_*_VALUE macros are
(MODULE_ALIAS_DSA_TAG_DRIVER hinges on those macro definitions).

But there is no reason to expose these helpers to <net/dsa.h>. That
header is shared between switch drivers (drivers/net/dsa/), tagging
protocol drivers (net/dsa/tag_*.c), the DSA core (net/dsa/ sans tag_*.c),
and the rest of the world (DSA master drivers, network stack, etc).
Too much exposure.

On the other hand, net/dsa/dsa_priv.h is included only by the DSA core
and by DSA tagging protocol drivers (or IOW, "friend" modules). Also a
bit too much exposure - I've contemplated creating a new header which is
only included by tagging protocol drivers, but completely separating a
new dsa_tag_proto.h from dsa_priv.h is not immediately trivial - for
example dsa_slave_to_port() is used both from the fast path and from the
control path.

So for now, move these definitions to dsa_priv.h which at least hides
them from the world.
