soc/intel/jasperlake: Run pmc_set_acpi_mode() during .init in pmc_ops

pmc_set_acpi_mode will set EC SMI mask to 1 in the end.
However google_chromeec_events_init will clear EC SMI mask.
If google_chromeec_events_init is ran after pmc_set_acpi_mode, the EC SMI mask
will be 0 in depthcharge and causes lidclose function not working.
So, pmc_set_acpi_mode() should run after google_chromeec_events_init.

This code is mainly from CB:42677

BUG=b:16338215
TEST=Close lid in depthcharge and the dut can be shutdown on waddledoo.
