ARM: zynq: Synchronise zynq_cpu_die/kill
Avoid races and add synchronisation between the arch specific kill and die routines. The same synchronisation issue was fixed on IMX platform by this commit: "ARM: imx: fix sync issue between imx_cpu_die and imx_cpu_kill" (sha1: 2f3edfd7e27ad4206acbc2ae99c9df5f46353024) Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
