    ar71xx: remove obsolete '< KERNEL_VERSION(3, 15, 0)' checks
    
    Because the oldest supported kernel version on the ar71xx target is 4.4,
    the condition that the kernel version is smaller than 3.15.0 is always
    false. Remove the obsolete checks from the target specific source files
    to clean up the code a bit.
