soc/intel/{adl,tgl,jsl}: Enable power button smi after BS_CHIPS_EXIT
On tgl, we noticed system hang if a shutdown is triggered before fsps. The dut is unable to shutdown properly due to tcss is stuck before tcss_init in fsps. This change enable power button smi on jsl, tgl, adl after fsps. it can also prevent a shutdown failure due to lack of fsps init on certain ip. BUG=b:186194102, b:186815114 TEST=Power on the system and pressing power button repeatedly doesn't cause the system hang during shutdown.
