dt-bindings: touchscreen: trivial-touch: Drop 'interrupts' requirement for old Ilitek
The old Ilitek touch controllers V3 and V6 can operate without
interrupt line, in polling mode. Drop the 'interrupts' property
requirement for those four controllers. To avoid overloading the
trivial-touch, fork the old Ilitek V3/V6 touch controller binding
into separate document.
