sandbox: pmic: Correct i2c pmic emulator platdata method

Browse source 
This currently reads the uclass's private data in the ofdata_to_platdata
method which is not allowed, since the uclass has not read it from the
device tree. This happens in the probe method.

Fix it by adding a probe() method and moving the code there.
