It doesn't look like that patch ever made it into mainline. Could you see if another patch in mainline resolves the bug by testing the mainline kernel? It can be downloaded from:

A quick search on the internet revealed this patch: https://lists.freedesktop.org/archives/intel- gfx/2017-March/124077.html. Applying it to the 4.4.0-122 kernel does indeed make the HDMI work Could you please cherry-pick this patch into the Ubuntu kernel? Thanks!
