Sandybridge doesn't support y-tiling for surface formats with 16 or
more bpp. There was previously an override to explicitly allow this
for Gen7. However, this restriction is also removed in Gen8+ so we
should use y-tiling there too.
This is important to do for Skylake which doesn't support x-tiling for
3D surfaces.
