Jinyang He fdd85e04df MIPS: zboot: Avoid endless loop in clear BSS. ...

Commit 2ee1503e54 ("MIPS: zboot: head.S clean up").

After .noreorder removed, clear BSS fall into endless loop. The bne
instruction will add nop to the delay slot at compile time. So a0
register will not increment by 4. Fix it and clear BSS from _edata
to (_end - 1).
