[U-Boot] [PATCH 2/2] microblaze: move ENV onto top of flash

[Stephan Linz]

On Microblaze systems with BPI configuration from CFI flash
the first 1-10 MB will occupied by the FPGA configuration
data (BIN file). So we can not use this area for the U-Boot
environment.

In most of all FPGA configuration cases the upper sector in
flash memory will be free for individuell usage.
