Subject: [PATCH -next] sched/topology: Make some symbols static

The sparse tool complains as follows:

kernel/sched/topology.c:211:1: warning:
 symbol 'sched_energy_mutex' was not declared. Should it be static?
kernel/sched/topology.c:212:6: warning:
 symbol 'sched_energy_update' was not declared. Should it be static?

This symbol is not used outside of topology.c, so this
commit marks it static.
