Subject: [USB]Add quirk for Samsung Android phone modem

[USB]Add quirk for Samsung Android phone modem
My Galaxy Spica needs this quirk when in modem mode, otherwise
it causes endless USB bus resets and is unusable in this mode.
Unfortunately Samsung decided to reuse ID of its old CDMA phone SGH-I500
for the modem part.
That's why in addition to this patch the visior driver must be prevented
from binding to SPH-I500 ID, so ACM driver can do that.
