kingst-la2016: remove unnecessary initialisation code

The OEM software communicates with device IC U10 to perform challenge-response
authentication, ensuring the device is genuine. We have no knowledge of the
obfuscation or encryption method used. Additionally it is a rolling code, so
the response changes even with same challenge. In any case, we can just ignore
this IC U10, it does not hinder sigrok support. Removing this code from
the initialisation routine. See schematic in wiki for more info on U10.
