drm/i915/glk: ECS Liva Q2 needs GLK HDMI port timing quirk

Browse Source 
The quirk added in upstream commit 90c3e21987 ("drm/i915/glk: Add
Quirk for GLK NUC HDMI port issues.") is also required on the ECS Liva
Q2.

Note: Would be nicer to figure out the extra delay required for the
retimer without quirks, however don't know how to check for that.
