    AMD Fam14 DSDT: Remove INI method from AZHD device
    I am removing the _INI method from the AZHD device because
    it does not seem to do anything and causes errors in the
    FWTS[1] (Firmware Test Suite) test 'method'. The INI
    method performs device specific initialization and is
    run when OSPM loads a description table.  It must only
    access OperationRegions that have been indicated as
    available by the _REG (Region) method.  We do not have a
    _REG method and during my testing, I added a REG method
    but it did not seem to make a difference in the PCI
    register space.  The bit fields defined as NSDI (Disable
    No Snoop), NSDO (Disable No Snoop Override), and NSEN
    (Enable No Snoop Request) do not ever get written from
    their default values.  And writing to these bit fields
    does not seem to be necessary because I did not notice
    any change in audio functionality.
    In an effort to clean up as many FWTS errors as possible,
    I propose removing this method altogether.  I have seen no
    change in operation (audio works with and without this
    method) and there does not seem to be any change in lspci
    or dmesg.
