libata: implement more acpi filtering options
Currently libata-acpi can only filter DIPM among SATA feature enables via _GTF. This patch adds the capability to filter out FPDMA non-zero offset, in-order guarantee and auto-activation. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
