dsa: simplify Kconfig symbols and dependencies
1. Remove CONFIG_HAVE_NET_DSA. CONFIG_HAVE_NET_DSA is a legacy leftover from the times when drivers should have selected CONFIG_NET_DSA manually. Currently, all drivers has explicit 'depends on NET_DSA', so this is no more needed. 2. CONFIG_HAVE_NET_DSA dependencies became CONFIG_NET_DSA's ones. - dropped !S390 dependency which was introduced to be sure NET_DSA can select CONFIG_PHYLIB. DSA migrated to Phylink almost 3 years ago and the PHY library itself doesn't depend on !S390 since commit 870a2b5e4fcd ("phylib: remove !S390 dependeny from Kconfig"); - INET dependency is kept to be sure we can select NET_SWITCHDEV; - NETDEVICES dependency is kept to be sure we can select PHYLINK. 3. DSA drivers menu now depends on NET_DSA. Instead on 'depends on NET_DSA' on every single driver, the entire menu now depends on it. This eliminates a lot of duplicated lines from Kconfig with no loss (when CONFIG_NET_DSA=m, drivers also can be only m or n). This also has a nice side effect that there's no more empty menu on configurations without DSA. 4. Kbuild will now descend into 'drivers/net/dsa' only when CONFIG_NET_DSA is y or m. This is safe since no objects inside this folder can be built without DSA core, as well as when CONFIG_NET_DSA=m, no objects can be built-in.
