Subject: [PATCH v2 2/2] extcon: max77843: add device-tree compatible string

Add the needed device-tree compatible string to the MAX77843 extcon
driver, so it can be automatically loaded when compiled as a kernel
module and given device-tree contains separate 'muic' node under the main
MAX77843 PMIC node.
