[PATCH 04/20] drm/amd/display: Hook up DAC to bios_parser_encoder_control

[Timur Kristóf]

The BIOS parser already supports calling the DAC1EncoderControl
function from the VBIOS, but it was not exposed anywhere.
This commit enables the codebase to use encoder_control()
when the encoder engine is one of the DACs.
