    virtio: add virtio framework in NuttX

    1. virtio devics/drivers match and probe/remote mechanism;
    2. virtio mmio transport layer based on OpenAmp (Compatible with both
       virtio mmio version 1 and 2);
    3. virtio-serial driver based on new virtio framework;
    4. virtio-rng driver based on new virtio framework;
    5. virtio-net driver based on new virtio framework
       (IOB Offload implementation);
    6. virtio-blk driver based on new virtio framework;
    7. Remove the old virtio mmio framework, the old framework only
       support mmio transport layer, and the new framwork support
       more transport layer and this commit has implemented all the
       old virtio drivers;
    8. Refresh the the qemu-arm64 and qemu-riscv virtio related
       configs, and update its README.txt;

    New virtio-net driver has better performance
    Compared with previous virtio-mmio-net:
