Add a driver for the NVMe storage controller integrated on Apple SoCs. This NVMe controller isn't PCI based and deviates from the NVMe standard in its implementation of the command submission queue and the integration of an NVMMU that needs to be managed. This commit tweaks the core NVMe code to support the linear command submission queue implemented by this controller. But setting up the submission queue and managing the NVMMU controller is handled by implementing the driver ops that were added in an earlier commit.
