[U-Boot] [PATCH] zlib: updated to v.1.2.3

Hi Jean Christophe,

thanks for your reply.

I tested u-boot over sh platforms and no size impact happens (just
differencies of few bytes, you can verify this by yourself)
About performances, really I obtain a 15% improvement during decompression.
Moreover I have to say that, working for my company, we have improved more
and more u-boot time just applying other patches regarding different area
other than the zlib common one.

Please, let me know if my patch will be useful for the community.
Best Regards,
Giuseppe

could you specify the size impact and performance impact?
and on which board do you test it?
