b45f9a3ed4 drm/amd/display: Remove redundant hdcp display state
[Why]
Due to previous code changes displays which are in active state
immediately transition to the active and added state. This makes the two
states redundant and unnecessary.

[How]
Instead of updating the device state to active and added after
successful addition, change state to inactive if addition failed. Also,
change references to active and added state to just added state.

a09f8e295c drm/amd/display: Move mod_hdcp_displays to mod_hdcp struct
[Why]
Reset connection is called before remove display in mod_hdcp. When
remove display is called, the display structure has been zeroed from
reset connection. Since no displays can be found, remove display does
not properly reset the hardware. This causes validation errors when
another display is plugged into a different port afterwards.

[How]
Moved displays structure out of connections structure. Displays
structure is now directly within mod_hdcp. Displays is no longer zeroed
when reset connection is called.

c17f7220f5 drm/amd/display: Handle revoked receivers
[Why]
PSP added a new return code for revoked receivers (SRM). We need to
handle that so we don't retry hdcp

This is already being handled on windows

[How]
Add the enums to psp interface header and handle them.

23eb41917f drm/amd/display: add force Type0/1 flag
[Why]
Before we had a disable_type1 flag, this forced HDCP 2.2 to type0
There was no way to force type1.

[How]
Remove disable_type1 flag and instead add a flag to force type0/1.
