drm/radeon/kms: add irq mitigation code for sw interrupt.
We really don't need to process every irq that comes in, we only really want to do SW irq processing when we are actually waiting for a fence to pass. I'm not 100% sure this is race free esp on non-MSI systems so it needs some testing. Signed-off-by: Dave Airlie <airlied@redhat.com>
