core/pci: Support PCI slot
Every PCIE bridge port or PHB is expected to be bound with PCI slot
, to which various PCI slot's functionalities are attached (e.g. power,
link, reset). This supports PCI slot:
* PCI slot is reprsented by "struct pci_slot".
* "struct pci_slot_ops" represents the functions supported on the
PCI slot. It's initialized by PCI slot core at the beginning and
allowed to be overrided by platform partially or completely.
* On PCI hot plugging event, the PCI devices behind the slot are
enumarated. Device sub-tree is populated and sent to OS by OPAL
message.
* On PCI hot unplugging event, the PCI devices behind the slot are
destroyed. Device sub-tree is removed and the slot is powered off.
