extcon: sm5502: Add support new SM5502 extcon device driver
This patch add new SM5502 MUIC(Micro-USB Interface Controller) device by using EXTCON subsystem. The extcon-sm5502 driver is capable of identifying the type of the external power source and attached accessory. An external power sources, such as Deticated Charger or a standard USB port, are able to charge the battery in the smart phone via the connector. Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
