[ACPI] Bind PCI devices with ACPI devices
Implement the framework for binding physical devices with ACPI devices. A physical bus like PCI bus should create a 'acpi_bus_type', with: .find_device: For device which has parent such as normal PCI devices. .find_bridge: It's for special devices, such as PCI root bridge or IDE controller. Such devices generally haven't a parent or ->bus. We use the special method to get an ACPI handle. Uses new field in struct device: firmware_data http://bugzilla.kernel.org/show_bug.cgi?id=4277 Signed-off-by: David Shaohua Li <shaohua.li@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
