MIPS: SMP: Move the AP sync point before the calibration delay
In the calibration delay process, some resources are shared, so it's better to move it after the parallel execution part. Thanks to the patch optimizing CPU delay calibration, this change has no impact on the boot time improvements gained from CPU parallel boot.
