    AMD Fam16: Add OSC method to PCI0
    
    The _OSC method is used to tell the OS what capabilities it can
    take control over from the firmware.  This method is described
    in chapter 6.2.9 of the ACPI spec v3.0.  The method takes 4
    inputs (UUID, Rev ID, Input Count, and Capabilities Buffer) and
    returns a Capabilites Buffer the same size as the input Buffer.
    This Buffer is generally 3 Dwords long consisting of an Errors
    Dword, a Supported Capabilities Dword, and a Control Dword.
    The OS will request control of certain capabilities and the
    firmware must grant or deny control of those features.  We do not
    want to have control over anything so let the OS control as much
    as it can.
    
    The _OSC method is required for PCIe devices.  During Linux boot,
    an error is logged to dmesg if _OSC is not found.
