usb_charger_exit() functions for usb charger initialization and exit.
It will report to the usb charger when the gadget state is changed,

can implement the usb_charger_plug_by_gadget() function and usb_charger_exit()
function by getting 'struct usb_charger' from 'struct gadget'.

usb gadget state.
This patch doesn't yet integrate with the gadget code, so some functions
which rely on the 'gadget' are not completed, that will be implemented
in the following patches.
