With the phylib now being aware of the "reset-gpios" PHY node property,
there should be no need to frob the PHY reset in this driver anymore...

v3:
  - Resolve rejects due to the file being renamed, refresh the patch,
  - Added code to reset PHY on probe error,
  - Edit patch description,
  - Take over from Sergei,
  - Add Acked-by,

v2:
  - No changes.
