Subject: [PATCH v1 4/4] PCI: hotplug: Implement hotplug_is_native() only
 when CONFIG_ACPI=y

From: Bjorn Helgaas <bhelgaas@...gle.com>

hotplug_is_native() is used only by the acpiphp driver, so we only need to
implement the interface when CONFIG_ACPI=y.

Move the implementation under #ifdef CONFIG_ACPI and drop the unnecessary
stubs for the non-ACPI case.
