From: Deepak Das <deepak_das@mentor.com>

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.
