Bhawanpreet Lakha 4c283fdac0 drm/amd/display: Add HDCP module
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 |
+----+    <-----    +--------+                 +--------------+
