Comment 3 Imre Deak 2019-08-09 14:11:09 UTC 
The problem is 
<7>[   10.069905] [drm:intel_bios_port_aux_ch [i915]] using AUX B for port C (VBT)
which is impossible. Port C is a TypeC port and can only be connected to an AUX starting from AUX C (and the AUX depending on the corresponding DP-Alt/TBT power well).

In addition either the rework for legacy-DP functionality is missing from the RVP or the BIOS setup is not configured accordingly.

So this is again a VBT issue wrt. the port C information in it. Please assign to someone who could generate a new VBT, removing the port C info from there completely, or fixing the AUX info in it (if the fi-icl-dsi has indeed the required DP rework).
