Hi Marek, kernel test robot noticed the following build warnings: [auto build test WARNING on dtor-input/next] [also build test WARNING on dtor-input/for-linus hid/for-next linus/master v6.6-rc4 next-20231005] [If your patch is applied to the wrong git tree, kindly drop us a note.

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.
