USB: Use menuconfig objects

commit 04d06ad0f1fdb499af84ae3d7969e2136a462f38 have added menuconfig support
for the whole USB Kconfig, but there are still menuconfig need for usb/serial,
usb/atm, and usb/gadget, so that the user can disable all the options in that
menu at once instead of having to disable each option separately.
