    kernel: add kmod-nvme package
    
    Add driver for NVM Express block devices, ie. PCIe connected SSDs.
    
    Targets which allow booting from NVMe (x86, maybe some mvebu boards come
    to mind) should have it built-in, so rootfs can be mounted from there.
    For targets without NVMe support in bootloader or BIOS/firmware it's
    sufficient to provide the kernel module package.
    
    On targets having the NVMe driver built-in the resulting kmod package
    is an empty dummy. In any case, depending on or installing kmod-nvme
    results in driver support being available (either because it was already
    built-in or because the relevant kernel modules are added and loaded).
