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. When device is instantiated from device-tree,
the driver data cannot be read via platform_get_device_id(), so get
device type from the parent MFD device instead, what works for both
cases.
