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.
