dboards: Added ability to register a per-dboard container class

- The typical dboard classes are actually "subdev" classes i.e.
  there is one instance per dboard subdev (front-end). This makes
  it hard to implement shared functionality between multiple
  front-ends.
- This changes adds the ability to create a container class which
  is created per group of subdevs and each subdev gets a pointer
  to the container class for cross linkage.
