This should probably say what the interrupt is used for. And once you
have that, remove the comment about it being unused in the driver. DT
is OS agnostic, so "driver" is very unspecific and your claim may
actually be false.

As per my understanding, they are generated by hardware but no usage of 
pwm interrupts as of now.

I am not sure if removing the entire entry is a good idea.
What would be the best way to represent that information ?

May be this ?

+-interrupts: one interrupt per PWM channel. No usage in HiFive 
Unleashed SoC.
