core/pci: Claim surprise hotplug capability
This claims PCIe surprise hotplug capability through device node's
property "ibm,slot-surprise-pluggable". The slot has the capability
when surprise hotplug is supported in its slot's capability bits or
link state change reporting is supported in PCIe link capability bits.
In order for link state events to be properly raised during surprise
hotplug, the power supply to the slot should be always on. The slot's
power state should be switched accordingly during fundamental reset.
