powerpc/eeh: I/O chip PE reset

Browse source

The patch adds the I/O chip backend to do PE reset. For now, we
focus on PCI bus dependent PE. If PHB PE has been put into error
state, the PHB will take complete reset. Besides, the root bridge
will take fundamental or hot reset accordingly if the indicated
PE locates at the toppest of PCI hierarchy tree. Otherwise, the
upstream p2p bridge will take hot reset.
