This reverts commit 98e6e286, as Yinghai Lu reports that it breaks kexec with at least the e1000 and e1000e drivers. The reason is that the shutdown sequence puts the hardware into D3 sleep, and the commit causes us to claim that it then is in D0 (running) state just because we don't understand the PM capabilities. Which then later makes "pci_set_power_state()" not do anything, and the device never wakes up properly and just returns 0xff to everything.
