Extcon: add MAX8997 extcon driver
This patch add extcon-max8997 driver to support the muic feature
of Maxim max8997 by using Extcon framework.
The extcon-max8997 driver is implemented based on 'drivers/misc/
max8997-muic.c' and then use Extcon interface instead of callback
function in struct max8997_muic_platform_data to notify cable state
of notifee which want to know always newly cable state when external
connector(e.g., USB, TA, JIG) is attached or detached.
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.
