input: touchscreen: fusion: use level triggered interrupt
Use level triggered interrupt which makes sure that even we miss a
rising edge (due to latencies in the kernel), the interrupt still
will be handled later, and doesn't freeze the input device.
(cherry picked from commit ef25b8a9f9c0ca7cc0f0f955d89d112c3e19f75b)
