x86, sched: Fix undefined reference to init_freq_invariance_cppc() build error

Browse Source 
[ Upstream commit 6c4ab1b86dac3954d15c00c1a6396d60a1023fab ]

The init_freq_invariance_cppc function is implemented in smpboot and depends on
CONFIG_SMP.

  MODPOST vmlinux.symvers
  MODINFO modules.builtin.modinfo
  GEN     modules.builtin
  LD      .tmp_vmlinux.kallsyms1
ld: drivers/acpi/cppc_acpi.o: in function `acpi_cppc_processor_probe':
/home/ray/brahma3/linux/drivers/acpi/cppc_acpi.c:819: undefined reference to `init_freq_invariance_cppc'
make: *** [Makefile:1161: vmlinux] Error 1
