PCI/ACPI: Handle PCI slot devices when creating/destroying PCI buses
Currently the pci_slot driver doesn't update PCI slot devices when PCI device hotplug event happens, which may cause memory leak and returning stale information to user. Now the pci_slot driver has been changed as built-in driver, so invoke PCI slot enumeration and destroy routines directly from the PCI core. And remove ACPI PCI sub-driver related code because it isn't needed any more.
