[POWERPC] pseries: Remove dead EEH video code

Remove dead code, and a misleading comment about EEH checking
for video devices.  The removed code is a left-over from the
olden days where there was concern over how video devices
worked in Linux. We are never going to go that way again,
so kill this.
