    mvebu: kernel: enable CONFIG_BLK_DEV_NVME
    
    CONFIG_BLK_DEV_NVME [1]:
    - This is a kernel driver for SSD connected to PCI or PCIe bus [1].
    By default, it is enabled for targets "ipq807x", "rockchip/armv8"
    and "x86/64".
    
    With miniPCIe adapter, there is a possibility to connect NVMe disk
    to Turris Omnia (cortex-a9), Turris MOX (cortex-a53).
    
    It allows to boot system from NVMe disk, because of that it can not
    be kmod package as you can not access the disk to be able to boot from
    it.
    
    CONFIG_NVME_CORE [2]:
    - This is selected by CONFIG_BLK_DEV_NVME
    It does not need to be explicitly enabled, but it is done for "ipq807",
    "x64_64" and rockchip/armv8", which has also enabled the previous config
    option as well.
    
    Kernel increase: ~28k KiB on mamba kernel
