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.
