linux-yocto/4.15: crypto: aes-generic - fix aes-generic regression on powerpc

Integrating the following upstream commit to fix gcc regression:

    crypto: aes-generic - fix aes-generic regression on powerpc

    commit 6e36719fbe90213fbba9f50093fa2d4d69b0e93c upstream

    My last bugfix added -Os on the command line, which unfortunately
    caused  a build regression on powerpc in some configurations.

    I've done some more analysis of the original problem and found
    slightly different workaround that avoids this regression and also
    results in better performance on gcc-7.0: -fcode-hoisting is an
    optimization step that got added in gcc-7 and that for all gcc-7 versions causes
    worse performance.

    This disables -fcode-hoisting on all compilers that understand the
    option. For gcc-7.1 and 7.2 I found the same performance as my previous
    patch (using -Os), in gcc-7.0 it was even better. On gcc-8 I could see
    no change in performance from this patch. In theory, code hoisting
    should not be able make things better for the AES cipher, so leaving it
    disabled for gcc-8 only serves to simplify the Makefile
    change.
