ACPICA: Major update for acpi_get_object_info external interface
Completed a major update for the acpi_get_object_info external interface. Changes include: - Support for variable, unlimited length HID, UID, and CID strings - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.) - Call the _SxW power methods on behalf of a device object - Determine if a device is a PCI root bridge - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO. These changes will require an update to all callers of this interface. See the ACPICA Programmer Reference for details. Also, update all invocations of acpi_get_object_info interface Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
