Switch_ON(): go into charging boot mode on either CHGSTS or CHGPRES If someone were to plug and then unplug a charger into a switched-off phone in an extremely brief "glitch" manner, we should do an automatic power-off on boot in this condition. When we were checking only CHGPRES in Switch_ON(), we would go into Misc boot state instead, which is undesirable. Now if we have a CHGSTS but not CHGPRES condition, we will go into charging boot mode, and FCBM will then do the automatic power-off upon detecting absence of the charger in its periodic polling.
