====================
DSA refactoring: set 1

There has been a long running effort to refractor DSA probing to make
the switches true linux devices. Here are a small collection of
patches moving in this direction. Most have been seen before.

We take a little step forward by passing the dsa device point to the
driver, thus allowing it to perform resource allocations using the
normal mechanisms. This device structure will later be replaced by the
devices own device structure.

Future patches will add a true driver probe function, so we rename the
current probe function, cleaning up the namespace.

phys_port_mask continually confuses me, thinking it is about PHYs. But
it is actually about ports enabled to the outside world. So rename it to
enabled_port_mask.

Lots more patches yet to follow, this is just doing some ground work.

v2:
  enabled_port_mask instread of user_port_masks
