Extcon: Add MAX8997 extcon driver for MUIC feature

This patchset use Extcon framework in extcon-max8997 driver to control external connector instead of max8997-muic driver which is implemented with callback function through platform_data to control external connector.

So, first patch add MAX8997 extcon driver (drivers/extcon/extcon-max8997.c), the last patch remove previous MAX8997 MUIC driver(drivers/misc/max8997-muic.c)
which support MUIC feature of Maxim MAX8997 with callback function.

v1
- Use Extcon interface to notify cable state of notifee instead of callback function when external connector is attached or detached.
- Bug fix of getting platform_data for irq_base value.

v2,v3
- Fix line-wrapping problem
