What is a "zero-depth pipeline" (from https://github.com/beagleboard/pocketbeagle/wiki/FAQ)? That's a CPU which isn't pipelined, like the 80386, or something else?

Yes. The "zero-depth pipeline" is in relation to the Programmable Real-Time Units (PRUs) that are part of the AM335x. The PRUs are separate CPUs from the Cortex A8 that allow the AM335x inside the OSD335x-SM to perform real-time, low-latency operations, like industrial or motor control.
