[PATCH 4/4] drm/radeon/kms: add wait idle ioctl for eg->cayman

[Dave Airlie <airlied@gmail.com>]

From: Dave Airlie <airlied@redhat.com>

None of the latest GPUs had this hooked up, this is necessary for
correct operation in a lot of cases, however we should test this on a few
GPUs in these families as we've had problems in this area before.
