Some board manufacturers hardcode the EDID for the embedded
panel in the VBIOS. This EDID should be used when the panel
doesn't have a DDC.

For reference, see the legacy non-DC display code:
amdgpu_atombios_encoder_get_lcd_info()

This is necessary to support embedded connectors without DDC.

The VBIOS has a function called ExternalEncoderControl which
controls the DP bridge encoders that some GPUs use for analog
and LVDS output. Fixup this old functionality.

For reference, see the legacy non-DC amdgpu display code:
amdgpu_atombios_encoder_setup_external_encoder()

- Set same parameters for the ENABLE action as the SETUP action
- Add missing enum values for DDC setup and DAC load detection
- Fix the bits per color field
- Clarify the code that sets the link rate
- Expose the function so that it can be called by rest of DC

A subsequent commit will call this function from DCE HWSS.

Pass the correct enum values as expected by the VBIOS.
Previously the actual bit depth integer value was passed,
which was a mistake.
