When a Uicc Card is inserted or removed, Android pops up a prompt
to the user to reboot the device. This prompt is unnecessary if the
modem supports Hot Swapping of cards.
Introduce a new config item to indicate if the modem supports
hotswapping. Frameworks can then check this before propmting the
user.
