misc: MAX8997: Remove max8997-muic driver

This patch remove old max8997-muic drvier because of newly Extcon framework.
Extcon framework manages the external connector, so add extcon-max8997 driver
by using Extcon interface to support MUIC feature of Maxim 8997 PMIC instead
of max8997-muic driver(drivers/misc/max8997-muic.c).
