meta-netboot: enable NBD and Ramdisk support in kernel config
NBD and Ramdisk support are required in the kernel to have the root filesystem mounted as an NBD device: * ramdisk is required to load the initrd (not an initramfs) * NBD is required to mount the root device from a remote NBD server Change-Id: Ib726714adfb549eaeb21f96e7bf874290e700a8b Signed-off-by: Stephane Desneux <stephane.desneux@iot.bzh>
