This module manages HDCP for amdgpu driver. The module behaves as a
state machine which handles the different authentication states of HDCP
The module is divided into 3 major components
+--------+
| Hdcp.c |
+--------+
Manages the state machine, sends the events to be executed and communicates
with the dm
+-----------+
|Execution.c|
+-----------+
This executes events based on the current state. Also generates
execution results as transition inputs
+------------+
|Transition.c|
+------------+
Decides the next state based on the input and makes requests to
hdcp.c to handle.
+-------------+
------> | Execution.c | ------
| +-------------+ |
| V

| DM | -----> | Hdcp.c | <------------ | Transition.c |
