Shrink the environment size for 3 reasons:
- reading the environment it is slow, therefore having a smaller env improves the speed. - usually in the environment there are only few variables, therefore the enviromnent is almost empty. - because the same image can run on different boards which may have different flashes with different page sizes, the CONFIG_ENV_SECT_SIZE can't be change, it is set to least common multiple of the page sizes.
Adding this change improves the boot time. Before update for reading the entire environment it took ~850 msec, after the change it takes ~40 msecs.
