The sdvo hotplug support check and activation has worked by coincidence for TMDS0. The boolean value returned by intel_sdvo_supports_hotplug() was masked with a bit shifted by device number, which also should have been one of SDVO_OUTPUT_* bits instead. Boolean true masked with 1 shifted by 0 just happened to match SDVO_OUTPUT_TMDS0...
Get hotplug support as a bit mask, check the correct bits for support, and use the correct bits for activating hotplug support.
