When multiple NVMe controllers are being initialized during spdk_nvme_probe(), we can overlap the hardware resets of all controllers to improve startup time. Rewrite the initialization sequence as a polling function, nvme_ctrlr_process_init(), that maintains a per-controller state machine to determine which initialization step is underway. Each step also has a timeout to ensure the process will terminate if the hardware is hung. Currently, only the hardware reset (toggling of CC.EN and waiting for CSTS.RDY) is done in parallel; the rest of initialization is done sequentially in nvme_ctrlr_start() as before. These steps could also be parallelized in a similar framework if measurements indicate that they take a significant amount of time.
