bcm63xx: add ethernet support for bcm6368

Browse source 
Add basic support for the internal ethernet switch on bcm6368. It behaves
as a dumb switch for now, but allows basic connectivity.

Also drop the ethernet patch for bcm6345 for now, it needs rework.

Subject: [PATCH 19/63] NET: bcm63xx_enet: move phy_(dis)connect into probe/remove
Only connect/disconnect the phy during probe and remove, not during any
open/close. The phy seldom changes during the runtime, and disconnecting
the phy during close will prevent it from keeping any configuration over
a down/up cycle.
