dsa: Hide core config options; make drivers select what they need
Commit 82167cb8c6b2f8166d5c7532e5ef4b5e0cc46a72 ('net: dsa/slave: Fix compilation warnings') fixed one possible invalid configuration (NET_DSA enabled with no trailer formats) but added others: drivers can select NET_DSA without its dependencies being met. It's not very useful to make either the DSA core or the tagging formats manually selectable without a driver to use them, so: 1. Define a hidden HAVE_NET_DSA option and move the dependencies of NET_DSA to that. While we're at it, drop the deprecated EXPERIMENTAL dependency. 2. Make NET_DSA and the drivers dependent on HAVE_NET_DSA. 3. Hide the tagging format options again. 4. Make drivers select both NET_DSA and the appropriate tagging format option.
