This series adds support for analog connectors to DC for DCE6-10. There are two reasons to add this support:
1. GPUs that already use DC by default and have analog connectors. Some Tonga and Hawaii graphics cards in fact have DVI-I connectors, and the analog part doesn't work by default. This functionality regressed when switching from the amdgpu legacy display code to DC. 2. GPUs that don't use amdgpu by default yet. Currently, SI (GFX6) and CIK (GFX7) don't use amdgpu by default yet, and missing analog connector support is cited as one of the main reasons why not. With this analog support added to DC, we could already fully switch CIK discrete GPUs to use DC and switch them to the amdgpu driver. For GFX7 APUs and SI, further fixes are needed before enabling DC. Before starting this work, I asked Harry and Alex about how best to do it and we agreed that we'd like to use the VBIOS to set up the DAC. So I used the amdgpu legacy display code as a reference. The first few commits add some minor changes to DC to prepare for supporting analog stream and link encoders, then analog link detection is added along with polling, and finally DAC load detection support, which is useful for old displays and adapters. Please let me know what you think.
