[Why]
IGT CRC tests fail on replay panels due to invalid CRC values
captured when replay is active.
[How]
- Disable replay when CRC source is enabled; set flag to
prevent unexpected re-enable
- Reset flag when CRC source is disabled to allow replay

[WHY]
Panel Replay is not an eDP-specific function.
[HOW]
Create new Panel Replay source files and move the Panel Replay
functions from the eDP files to the new files. Additionally, create
a new link_service construct function to assign the related
function pointers.

[WHY]
Header file name "link.h" collides with system header when dc is
compiled as a user-mode library
[WHAT]
Rename link.h to link_service.h to avoid name collision

[Why & How]
User can get the panel replay capability and state for debug.
sudo cat /sys/kernel/debug/dri/0/eDP-1/replay_capability
"Sink support: no" - if panel doesn't support Replay
"Sink support: yes" - if panel supports Replay
"Driver support: no\n" - if driver doesn't support Replay
"Driver support: yes\n" - if driver supports Replay
sudo cat /sys/kernel/debug/dri/0/eDP-1/replay_state
It will return current panel replay state

[Why]
Enable the Panel Replay if eDP panel and ASIC support.
(prioritize Panel Replay over PSR)
[How]
- Setup the Panel Replay config during the device init
(prioritize Panel Replay over PSR).
- Separate the Replay init function into two functions
amdgpu_dm_link_setup_replay() and amdgpu_dm_set_replay_caps()
to fix the issue in the earlier commit that cause PSR and Replay
enabled at the same time.

We need to make sure that the panel supports replay.
This info is inside the amd vsdb (vendor specific data block). Create a
function to parse the block and read the replay_mode bit.

We need certain conditions for replay to be enabled, so create an
interface in DM to enable/disable replay.
