[U-Boot] [PATCH 15/18] malta: store environment in flash

[Paul Burton]

Allow the environment to be stored in the monitor flash of a Malta
board. The environment is stored in the final 128KB of the flash, which
both leaves the majority of the flash available for U-boot code and also
matches the location which YAMON uses.
