regulator: pwm: Fix handling of missing init voltage
Since priv->init_voltage is an unsigned integer it can never be
negative. So the current code fails to detect a missing
'regulator-init-microvolt' property and instead misconfigures the
PWM device. Fix this by making the relevant members of
'struct pwm_regulator_info' signed integers.
