Add the binding description and the corresponding driver for
the BD2606.

Changes in V6:
- comments about dealing with shared brightness registers
- comment about building as a module

Changes in V5:
- remove "driver" from the binding subject line
- avoid presenting shared brightness to the userspace
  by allowing only on/off in such cases.

Changes in V4:
- minor tuning of description in bindings
 
Changes in V3:
- binding cleanup
- move active variable from long-living struct onto stack

Changes in V2:
- Add Datasheet link
- use fwnode api
- remove childnode count check, that will bail out
  anyways later.
- add enable-gpios to binding but not to driver due to lack of
  testing ability
