intel/isl: tile 64 calculations work with 1D surfaces

Depth/stencil surfaces cannot be linear but they can be 1D, so they
end up being tile64 when sparse (as we force every sparse resource to
be either tile64 or linear).

According to the "1D surfaces" page from BSpec, our driver treats 1D
surfaces as 2D surfaces with a height of 1 texel, since we don't
enable the corresponding bit from HAS_SLICE_CHICKEN7. And since we
support 2D surfaces, we should also support 1D.
