[PATCH] arm: dts: fix rk3066a based boards vdd_log voltage initialization

The current rk3066a based boards(Rayeager, Bqcurie2, Marsboard) use
pwm modulate vdd_logic voltage, but the pwm is default disabled and
the pwm pin acts as a gpio before pwm regulator probed, so the pwm
regulator driver will get a zero dutycycle at probe time, so change
the initial dutycycle to zero to match pwm_regulator_init_state check.
