ARM: dts: rk3288: add the interrupts property for PWM

We are assuming that PWM need use the property, we can support the
SPI interrupts for PWM.

At the moment, we can find the remotectl pwm is needed on box.
We can add the property for all PWMs. AFAIK, the pwm driver don't use it
but the drivers/input/remotectl/rockchip_pwm_remotectl.c
