touchscreen: fusion_F0710A: Reset controller if clear interrupt operation fails
Add support for resetting the controller using the gpio reset pin
if interrupt could not be cleared. If clearing the interrupt fails,
the interrupt line stays high and no further interrupts are generated
resulting in a non functioning touchscreen until next reboot, when we
reset the controller again in probe.
