This driver component provides support for using consumer NVMe storage devices, i.e. it omits name space managment and will always use the first name space, on Genode. For now it defaults to a reasonable low configuration: - 1 I/O queue (completion/submission tuple) - 128 entries in the I/O queue - 4096 as the only I/O transaction memory page size Fixes #2747.
