Fix both arge0 and arge1 to work correctly on the AP135.

Browse Source 
* Force the arge0 interface to not use a PHY for speed negotiation
  for now.  It'd be nice to do it, but right now the RGMII interface
  to the switch needs to stay at 1000/full in order to match what
  the switch side of the port is programmed as.

  So until that's all sorted out, disconnect arge0 from the PHY
  and leave it at fixed at 1000/full.

  I noticed this when I tried using a busted ethernet cable that
  forced the PHY to negotiate 100/full.  The switch was fine and
  it negotiated to 100/full, but then arge0 saw the link update
  and set the speed to 100/full when the switch side of that
  hook up was set to 1000/full.  Tsk.

* When using argemdio, the mdio device resets and initialises
  the MAC, /not/ the arge_attach (or, as I discovered, arge_init.)
  So arge1 wasn't being fully initialised and thus no traffic
  would ever flow.

  So until I tidy up that mess, just create an argemdio bus for
  arge1.  It's totally fine; it won't do anything or find anything
  attached to it.

Tested:

* AP135 reference board - both arge0 and arge1 now work.
