MIPS: smp-cps: function to determine whether CPS SMP is in use
The core power down state for cpuidle will require that the CPS SMP implementation is in use. This patch provides a mips_cps_smp_in_use function which determines whether or not the CPS SMP implementation is currently in use. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
