drm/amd/display: Add DCN3.1 DIO
Add support for the DIO (Display IO) block of DCN3.1 which controls
legacy HDMI/DP stream/link encoding.
HW Blocks:
+--------+ +--------+
| DIO | | DCCG |
+--------+ +--------+
Includes some updates to core logic for link encoder assignment and
future support for new high bandwidth output.
