ARM: shmobile: r8a7779: Remove redundant cpu_disable implementation
By default only the non-boot CPUs can be hotplugged if the smp_operations structure doesn't have the cpu_disable function pointer set. r8a7779_cpu_disable() implements the same logic, only non-boot CPUs can be hotplugged, so it's redundant to override the default behavior.
