[Intel-gfx] [PATCH 1/2] drm/dp: add defines for downstream port types

[Jani Nikula]

Detailed cap info at address 80h is not available with DPCD ver
1.0. Whether such devices exist in the wild I don't know, but there
should be no harm done in having the defines for downstream port 0 in
address 05h.
