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.

FC Tourmaline stdmodem functional configuration is equivalent to Magnetite hybrid. The only intentional diff from Magnetite to Tourmaline in the modem configuration is the change of Nucleus: Magnetite uses the blob version of Nucleus which came with TCS211-20070608, whereas Tourmaline uses the source version of Nucleus by Comrade XVilka. It is essentially a change from an unknown version of Nucleus to a known one, thus it should generally be considered an improvement - but as always with such changes, extensive verification and testing needs to be done in order to ensure that nothing got broken. Aside from the one intentional change of Nucleus version, FC Tourmaline is an entirely new firmware source tree, thus it is always possible that something could have got broken unintentionally, particularly in rarely-tested areas of the firmware. Therefore, extensive testing will need to be done before we can declare Tourmaline stdmodem as officially replacing Magnetite hybrid for stable modem products.
