arm64: sched: Remove unused mc_capable() and smt_capable()

Remove unused and deprecated mc_capable() and smt_capable().

Both were added recently by f6e763b9 ("arm64: topology:
Implement basic CPU topology support"). Uses of both were removed
by 8e7fbcbc ("sched: Remove stale power aware scheduling
remnants and dysfunctional knobs").
