Subject: [PATCH -next] ARM: zx: Make zx_smp_prepare_cpus static

Fix the following sparse warning:

arch/arm/mach-zx/platsmp.c:41:13: warning: symbol 'zx_smp_prepare_cpus' was not declared.

The zx_smp_prepare_cpus has only call site within platsmp.c
It should be static

Fixes: 71bc724300e6 ("ARM: zx: enable SMP and hotplug for zx296702")
