microblaze: Fix stack protection behavior

When U-Boot starts stack protection can be already enabled that's why setup
the lowest possible SLR value which is address 0. And the highest possible
stack in front of U-Boot. That's why you should never load U-Boot to the
beginning of DDR. There must be some space reserved. Code is using this
location for early malloc space, early global data and stack.
