drm/amd/display: Restore analog connector support

Browse source

[Why]
The analog connector support was accidentally removed,
causing a crash when connecting an analog monitor.

[How]
This patch restores the functions and pointers required for proper analog
and DP bridge encoder support on legacy GPUs.

V2: Restore the external encoder control functions.

V3:
 - Restore BIOS parser external encoder DAC load detection
 - Restore stream initialization and source selection changes
