PCI hotplug: introduce functions for ACPI slot detection

Some ACPI related PCI hotplug code can be shared among PCI hotplug drivers. This patch introduces the following functions in drivers/pci/hotplug/acpi_pcihp.c to share the code, and changes acpiphp and pciehp to use them. - int acpi_pci_detect_ejectable(struct pci_bus *pbus) This checks if the specified PCI bus has ejectable slots. - int acpi_pci_check_ejectable(struct pci_bus *pbus, acpi_handle handle) This checks if the specified handle is ejectable ACPI PCI slot. The 'pbus' parameter is needed to check if 'handle' is PCI related ACPI object. This patch also introduces the following inline function in include/linux/pci-acpi.h, which is useful to get ACPI handle of the PCI bridge from struct pci_bus of the bridge's secondary bus. - static inline acpi_handle acpi_pci_get_bridge_handle(struct pci_bus *pbus) This returns ACPI handle of the PCI bridge which generates PCI bus specified by 'pbus'.
