Persimmon 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.
