microblaze: u-boot.lds: replace __end symbol with _end

Browse Source 
board_fdt_blob_setup() uses the _end symbol to find the dtb in the non-spl
case. In order to allow microblaze builds to compile successfully with
CONFIG_OF_SEPARATE, the _end symbol must be defined. Align microblaze with
the other architectures and use _end symbol rather than __end to mark the
end of the u-boot binary.
