    AMD Fam14 DSDT: Add OSC method
    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 and dmesg
    checks for its existence and issues an error if it is
    not found.
    This is the same change made to Persimmon with Change-ID
