usb: gadget: introduce UDC Class
this class will be used to abstract away several of the duplicated operations scattered among the USB gadget controller drivers. Later, we can add an atomic notifier to tell interested drivers about what's happening with the controller. Notifications such as suspend, resume, enumerated, etc. will be useful, at a minimum, for implementing usb charger detection. As part of the converting process usb_gadget_probe_driver() is no longer part of each udc but pushed into the ->stap() callback. The same for his couterpart. The core is currently set explicit to 'n'. It will be changed to 'y' once all users are converted since it provides functions which clash with other drivers.
