freedreno/ir3: disable texture prefetch for 1d array textures

freedreno/ir3: disable texture prefetch for 1d array textures

Prefetch only supports the basic 2D texture case, checking is_array is
needed because 1d array textures pass the coord num_components==2 test.

Fixes: 2a0d45ae ("freedreno/ir3: Add a NIR pass to select tex instructions eligible for pre-fetch")
