This patch introduces the usb charger support based on usb phy that makes an enhancement to a power driver. The basic conception of the usb charger is that, when one usb charger is added or removed by reporting from the extcon device state change, the usb charger will report to power user to set the current limitation. Power user can register a notifiee on the usb phy by issuing usb_register_notifier() to get notified by charger status changes or charger current changes. we can notify what current to be drawn to power user according to different charger type, and now we have 2 methods to get charger type. One is get charger type from extcon subsystem, which also means the charger state changes. Another is we can get the charger type from USB controller detecting or PMIC detecting, and the charger state changes should be told by issuing usb_phy_set_charger_state().
