ROC-PC is not able to boot linux console if PWM2_d is unattached to any pinctrl logic.
To be precise the linux boot hang with last logs as, ... ..... [ 0.003367] Console: colour dummy device 80x25 [ 0.003788] printk: console [tty0] enabled [ 0.004178] printk: bootconsole [uart8250] disabled
In ROC-PC the PWM2_d pin is connected to LOG_DVS_PWM of VDD_LOG. So, for normal working operations this needs to active and pull-down.
This patch fix, by attaching pinctrl active and pull-down the pwm2.
