We'll need a GET_PARAM ioctl param to say "we support RGBA64 textures"
and use that from vc4_screen.c's format checking, otherwise new Mesa on
old kernels will try to expose RGBA64 textures and fail at rendering
time.  If we're introducing a GET_PARAM, we probably want to just do
half float rendering and texturing at the same time.
