[USB]Add Samsung SGH-I500/Android modem ID switch to visor driver

Samsung decided to reuse USB ID of its old CDMA phone SGH-I500 for the
modem part of some of their Android phones. At least Galaxy Spica
is affected.

This modem needs ACM driver and does not work with visor driver which
binds the conflicting ID for SGH-I500.
Because SGH-I500 is pretty an old hardware its best to add switch to
visor
driver in cause somebody still wants to use that phone with Linux.

Note that this is needed only when using the Android phone as modem,
not in USB storage or ADB mode.
