arm64: dts: rockchip: Set pwm pin default pull setting when used for pwm regulator

Browse Source 
As a second global reset, the GRF is not reset, the iomux and
pull of PWM pin is still keeping, but PWM controller is reset,
PWM pin goes into input mode. However, the pull is still none
changed in kernel, which can cause voltage problems, so should
always keep the PWM pin pull down mode, with 0~50 μA power
increase.
