NVMe: Add nvme subsystem reset support Controllers part of an NVMe subsystem may be reset by any other controller in the subsystem. If the device is capable of subsystem resets, this patch adds detection for such events and performs appropriate controller initialization upon subsystem reset detection. The register bit is a RW1C type, so the driver needs to write a 1 to the status bit to clear the subsystem reset occured bit during initialization.
