anv/image: Fix usage for depthstencil images

The tests assertion-failed in vkCmdClearDepthStencilImage because the
isl surface lacked ISL_SURF_USAGE_DEPTH_BIT.

Fixes: https://gitlab.khronos.org/vulkan/mesa/issues/26
Fixes: dEQP-VK.pipeline.timestamp.transfer_tests.host_stage_with_clear_depth_stencil_image_method
Fixes: dEQP-VK.pipeline.timestamp.transfer_tests.transfer_stage_with_clear_depth_stencil_image_method
