asahi: Fix depth for cube maps

For cube maps, depth=1 in the hardware (but 6 in Gallium). Likewise for
cube map arrays, depth=n in the hardware (but 6n in Gallium). We need to
divide to compensate. This will be relevant for cube map arrays in the
future -- add the dimension XML for cube map arrays too.
