extcon: max8997: Consolidate duplicate code for checking ADC/CHG cable type
This patch make max8997_muic_get_cable_type() function to remove duplicate code for checking ADC/Charger cable type because almost internal function need to read adc/chg_type value of MUIC register. Also, remove *_detach() function, extcon-max8997 driver treat attach/detach operation of cable in max8997_*_handler() function. Lastly, this patch move defined constant in header file(include/ linux/mfd/max8997.h, max8997-private.h) because defined constant is only used in the 'extcon-max8997.c'.
