[PATCH 3/3] arm64: dts: rk3399: Add init voltage for vdd_log

[Kever Yang]

Since there is no devfreq used for vdd_log, so the vdd_log(pwm regulator)
will be 'enable' with the dts node at a default PWM state with high or low
output. Both too high or too low for vdd_log is not good for the board,
add init voltage for driver to make the regulator get into a know output.

Note that this will be used by U-Boot for init voltage output, and this
is very important for it may get system hang somewhere during system
boot up with regulator enable and without this init value.
