etnaviv: Supertiled texture support on gc3000
Support supertiled textures on hardware that has the appropriate
feature flag SUPERTILED_TEXTURE.
Most of the scaffolding was already in place in etna_layout_multiple:
case ETNA_LAYOUT_SUPER_TILED:
*paddingX = 64;
*paddingY = 64;
*halign = TEXTURE_HALIGN_SUPER_TILED;
So this is just a matter of allowing it.
