Currently Driver probe continues with a warning message when it
fails to get the proper multitouch object configurations like
TouchScreen resolution.

But Driver probe should fail in case of above scneario because it
will not behave as expected without the proper touchscreen
configurations.

This commit modifies mxt_initialize_input_device() to return error
when it fails to get the proper touch screen configurations.
