drm/amd/display: Add missing encoder setup to DACnEncoderControl

Browse Source 
Apparently the DAC encoder needs to be set up before use.
The BIOS parser in DC did not support this so I assumed it was
not necessary, but the DAC doesn't work without it on some GPUs.

Fixes: 69b29b8946 ("drm/amd/display: Hook up DAC to bios_parser_encoder_control")
