panfrost: Document "depth-buffer writeback" bit

This bit, if set, causes the depth buffer to be copied from GPU tile
memory to the provided depth buffer in main memory. If not set, the GPU
will not access the main memory (saving considerable memory bandwidth if
depth results are not actually used).
