microblaze: Use klimit instead of _end for memory init
For noMMU system when you use larger rootfs image there is problem with using _end label because we increase klimit but in memory initialization we use still _end which is wrong. Larger mtd rootfs was rewritten by init_bootmem_node. MMU kernel use static initialization where klimit is setup to _end. There is no any other hanling with klimit.
