Subject: [PATCH] Input: max77693-haptic - add device-tree compatible strings

Add the needed device-tree compatible strings to the MAX77693 haptic
driver, so it can be automatically loaded when compiled as a kernel
module and given device-tree contains separate (i.e. 'motor-driver')
node under the main PMIC node.
