[PATCH] arch: crash: Remove duplicate declaration in smp.h

[guoren]

From: Guo Ren <guoren@linux.alibaba.com>

Remove crash_smp_send_stop declarations in arm64, x86 asm/smp.h
which has been in include/linux/smp.h since 6f1f942cd5fb ("smp:
kernel/panic.c - silence warnings").

This patch is separated from the series [1] to let maintainer take
easily. It still needs a Acked-by from x86 side, hope it could be
soon done.

Thx.

Hi, Arnd

Because it crosses the architecture, could you take this in your next-tree?
