The usb charger framework is based on usb gadget, and each usb gadget
can be one usb charger to set the current limitation.

This patch adds a notifier mechanism for usb charger to report to usb
charger when the usb gadget state is changed.

Also we introduce a callback 'get_charger_type' which will implemented
by user for usb gadget operations to get the usb charger type.

You just broke the build, which proves you did not properly test this
patch series, so why should we even consider it?

Oh, I'm very sorry about that. I'll re-check my patch and test it
carefully. Thanks for your comments.
