amd/stoneyridge: Remove SATA D0 on suspend
Remove the step of setting the SATA controller to S0 as the system is entering S3. This had been duplicated from AMD's FchCarrizo.asl file, but upon closer inspection, the conditions for this step to run cannot be met. This does not affect Grunt's behavior, as the SATA controller is disabled. TEST=Suspend and resume Grunt BUG=b:77602074 Change-Id: Ib269a5363d03c7048abd0c8a9a28df92a773790c Signed-off-by: Marshall Dawson <marshalldawson3rd@gmail.com> Reviewed-on: https://review.coreboot.org/28863 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Martin Roth <martinroth@google.com>
