[U-Boot] [PATCH v4 6/7] nios2: define _end in link script

[Thomas Chou]

Since commit 44c6e6591cb451ae606f8bde71dd5fb7b4002544
"rename _end to __bss_end__" , the _end was removed.
But we need it now for separated device tree control,
ie, CONFIG_OF_SEPARATE .

The _end is used by fdtdec_setup() to find the blob.
