    brcm47xx: switch to the kernel 4.14
    
    The biggest (and the only?) disadventage of this is obviously an
    increased image size.
    
    For mips74k the size of vmlinux goes up from 4186684 B to 4701436 B.
    Most devices use LZMA compressed kernel so probably more important is
    vmlinux.lzma size which goes up from 1342945 B to the 1508498 B.
    
    Still this isn't something that should stop target kernel bump. There
    are various adventages of kernel 4.14. If kernel / image size is a
    serious concern for anyone, it's perfectly possible to use previous
    release which is pretty solid for the brcm47xx.
