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.]
