rfnoc: Add mb_controller API

The mb_controller is an interface to hardware-specific functions of the
motherboard. The API works in two ways:
- The user can request access to it, and thus interact directly with the
  motherboard
- RFNoC blocks can request access to it, if they need to interact with
  the motherboard themselves.
