    Recognise NVME devices (#755022)
    
    Add a pattern to recognise Non-Volatile Memory Express devices as valid
    devices to work with.  Devices are named by the Linux kernel device
    driver like /dev/nvme0n1 [1] with partitions named like /dev/nvme0n1p1
    [2].

    [2] Contents of /proc/partitions for a partitioned NVME device
        $ grep nvme /proc/partitions
         259        0  390711384 nvme0n1
         259        1        977 nvme0n1p1
         259        2   31250000 nvme0n1p2
         259        3  328209496 nvme0n1p3
         259        4   31249408 nvme0n1p4
    
    Bug 755022 - gparted doesn't recognize nvme devices
