mx31ads: Fix environment location on flash
At the moment u-boot and u-boot environment on flash have overlapping addresses, so each u-boot update erases the environment. Fix this by placing evironment right after u-boot. Also, remove confusing comment about environment location. Signed-off-by: Felix Radensky <felix@embedded-sol.com>
