[OE-core] [PATCH] kernel-devsrc: cp Documentation/ to sdk kernel

[Hongzhi.Song]

A new patch let kernel source Documentation/Kconfig in top Kconfig
So kernel-devsrc should include Documentation/ too.
Otherwise "make scripts" will fails.

    docs: Kbuild/Makefile: allow check for missing docs at build time

    While this doesn't make sense for production Kernels, in order to
    avoid regressions when documents are touched, let's add a
    check target at the make file.
