etnaviv: disable 64bpp render/sampler formats

Browse Source 
Vivante hardware handles 64bpp render targets and samplers in a odd way
by splitting the buffer and using a pair of texture samplers or a pair
of MRT outputs to access those resources. This isn't implemented in the
driver right now, so we should not advertise support for those formats.
