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.
