dt-bindings: timer: nuvoton: Clarify that interrupt of timer 0 should be specified

Browse Source 
The NPCM750 Timer/Watchdog Controller has multiple interrupt lines,
connected to multiple timers. The driver uses timer 0 for timer
interrupts, so the interrupt line corresponding to timer 0 should be
specified in DT.

I removed the mention of "flags for falling edge", because the timer
controller uses high-level interrupts rather than falling-edge
interrupts, and whether flags should be specified is up the interrupt
controller's DT binding.

Required properties:
- compatible : "nuvoton,npcm750-timer" for Poleg NPCM750.
- reg : Offset and length of the register set for the device.
- interrupts : Contain the timer interrupt with flags for
falling edge.
- interrupts : Contain the timer interrupt of timer 0.
- clocks : phandle of timer reference clock (usually a 25 MHz clock).
