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.
