PNP: mark resources that conflict with PCI devices "disabled"

Both the PNP/PCI conflict detection quirk and the PNP system
driver must use the same mechanism to mark resources as disabled.

I think it's best to keep the resource and to keep the type bit
(IORESOURCE_MEM, etc), so that we match the list from firmware
as closely as possible.

Fixes this regression from 2.6.25: http://lkml.org/lkml/2008/6/1/82
