hwmon: (adt7475) Use device_property APIs when configuring polarity
On DT unaware platforms of_property_read_u32_array() returns -ENOSYS
which wasn't handled by the code treating adi,pwm-active-state as
optional. Update the code to use device_property_read_u32_array() which
deals gracefully with DT unaware platforms.
