fw_setenv usage always locks u-boot-env mtd device without questions.
Locking of flash can be disruptive and may affect not only u-boot-env
region due to different problems with chips and lock callbacks on kernel
side. I'm not sure if my fix is right, but also I thought about possible option
in fw_env config about locking/unlocking or even option into
fw_setenv/printenv. Any ideas?
