[U-Boot] [PATCH 1/2] ARM: kirkwood: Enforce size limit for sheevaplug

The u-boot binary sits in flash immediately before the environment.
Don't allow the binary size to grow into the environment space.

This will actually result in a build failure. Which is what we want, at
least until https://lists.denx.de/pipermail/u-boot/2018-June/330467.html
is merged.
