Subject: [PATCH] arm: topology: make function static

Make function cpu_corepower_mask() static, as it is only referenced in
this file.

../arch/arm/kernel/topology.c:195:23: warning: no previous prototype for ‘cpu_corepower_mask’ [-Wmissing-prototypes]
 const struct cpumask *cpu_corepower_mask(int cpu)
                       ^~~~~~~~~~~~~~~~~~
