 rockchip,rk3128-pwm

Reduced CC.

Hi Rob,

The rk3328 and rv1108 PWM interrupt is chaired between blocks I think.
For rv1108 the same interrupt is used for all PWM nodes.
For rk3328 only added to one PWM node.
Currently not in use in a Linux drivers??

No consensus yet...on removing or parent node, so it stays as it is...
Maybe if you have ideas things will change. ;)
