base fork: P0-A1 — re-enable xHCI interrupt-driven operation

Update submodule pointer to cbd40e0d (base fork master).

Per USB-IMPLEMENTATION-PLAN.md v2 P0-A1: xhcid/src/main.rs:141 formerly
hardcoded (None, InterruptMethod::Polling), bypassing the complete
get_int_method() that handles MSI-X/MSI/INTx.  The IrqReactor's
run_with_irq_file path is fully wired and activates when irq_file is
Some — no other code assumed polling-only.

Oracle review confirmed correct register reads, loop continuation, and
EHB clearing already in the baseline.  P0-A1 is a single-line restore.
