Subject: [PATCH -next v2] sched/topology: Mark some symbols with static keyword

Fix the following sparse warnings:

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?

Fixes: 31f6a8c0a471 ("sched/topology,schedutil: Wrap sched domains rebuild")
