Dhinakaran Pandiyan 264ff016cf drm/i915/psr: Fall back to max. synchronization latency if DPCD read fails 
Noticed that we assume the best case of 0 latency when the DPCD read
fails, reasonable pessimism is safer.

eDP spec does say that if latency is greater than 8, the panel
supplier needs to provide it. I didn't see anything specific in the VBT
for this, so let's go with 8 frames as a fallback.
