drm/core: add ioctl to query device/driver capabilities
We're coming to see a need to have a set of generic capability checks in the core DRM, in addition to the driver-specific ioctls that already exist. This patch defines an ioctl to do as such, but does not yet define any capabilities. [airlied: drop the driver callback for now.] Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
