    ipq40xx: add MikroTik subtarget
    
    MikroTik devices require the use of raw vmlinux out of the self
    extracting compressed kernels.
    
    They also require 4K sectors, kernel2minor, partition parser as well as
    RouterBoard platform drivers.
    
    So in order to not add unnecessary code to the generic sub target lets
    introduce a MikroTik sub target.
