[PCI] duplicate sysfs symbols getting registered in current git

[Guennadi Liakhovetski]

Booting an x86 SMP PC with todays git-snapshot or just with 2.6.25-rc2 
getting the following warnings (with a bit of context):

* Found PM-Timer Bug on the chipset. Due to workarounds for a bug,
* this clock source is slow. Consider trying other clock sources
