Implement RPMB frontend
The RPMB frontend provides a high level read/write interface for
accessing the RPMB device and it does calls to the RPMB backend. This
component contains the main RPMB logic, including:
* Writing authentication key
* Handling the write counter
* Building and verifying RPMB data frames
