platform/x86: pcengines-apuv2: Drop platform:pcengines-apuv2 module-alias

The driver auto-loads based on the DMI modaliases and this platform
modalias is not necessary and broken:

1. Not necessary since the driver itself creates the platform_device,
   so it is already loaded when the modalias might be used
2. From a quick scan of the code it does not create any platform-devices
   called "platform:pcengines-apuv2"
