[lm-sensors] [PATCH] Don't probe EDID addresses on graphics card adapters

[Jean Delvare]

Avoid probing EDID addresses (0x50-0x57) on graphics card adapters.
We had one report that it caused trouble:
http://lists.lm-sensors.org/pipermail/lm-sensors/2012-April/035847.html
Even though it's not yet clear what happened, let's play it safe.

This closes ticket #2386.
