[Intel-gfx] [PATCH] drm/i915/glk: ECS Liva Q2 needs GLK HDMI port timing quirk

[Jani Nikula]

From: Diego Santa Cruz <Diego.SantaCruz at spinetix.com>

The quirk added in upstream commit 90c3e2198777 ("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.
