Subject: [PATCH] Documentation: Drop cpu0_hotplug mentions

This is gone since commit e59e74dc48a3 ("x86/topology: Remove CPU0
hotplug option"). zh_CN translation is also updated here, but needs
to be checked.

-CPU又可以使用了。这应该对所有的CPU都有效。CPU0通常比较特殊，被排除在CPU热拔插之外。
-在X86上，内核选项 *CONFIG_BOOTPARAM_HOTPLUG_CPU0* 必须被启用，以便能够关闭CPU0。
-或者，可以使用内核命令选项 *cpu0_hotplug* 。CPU0的一些已知的依赖性:
-
-* 从休眠/暂停中恢复。如果CPU0处于离线状态，休眠/暂停将失败。
-* PIC中断。如果检测到PIC中断，CPU0就不能被移除。
