dt-bindings: timer: renesas,tmu: Document input capture interrupt
Some Timer Unit (TMU) instances with 3 channels support a fourth
interrupt: an input capture interrupt for the third channel.
While at it, document the meaning of the four interrupts, and add
"interrupt-names" for clarity.
Update the example to match reality.
Inspired by a patch by Yoshinori Sato for SH.
