BG96 Test with NUCLEO_F429ZI

[heejungPark]

We only modified mbed_app.json as below and got a Log.txt.
Our Hardware connection is okay... but It looks like power of modem is not running.
For reference, This example(https://os.mbed.com/users/Daniel_Lee/code/mbed-os-example-cellular-BG96/) is running on our hardware setting.
Could you please check parameters and this log?
