soc/intel/apollolake: provide fake PM1 SMI status bit
It appears that PM1 is not wired up to the SMI status register, but it does definitely cause SMIs to trigger. Therefore, provide a fake PM1 status bit by checking the power button status when SMI status is indicating no status as well as the PM1 control indicating that SCI mode is not enabled. BUG=chrome-os-partner:54262 TEST=Smashed power button on reef to cause SMI in firmware. No longer loops infinitely with constant SMIs firing.
