gbm: track buffer format through DRI drivers
GBM needs the buffer format in order to communicate with DRM and clients for things like scanout. So track the DRI format requested in the various back ends and use it to return the DRI format back to GBM when requested. GBM will then map this into the GBM surface type (which is in turn based on the DRM fb format list). Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
