platform: int3472: discrete: con_id vana for Sony IMX471 as power enable

Browse Source 
Update the con_id for the Sony IMX471 sensor to "vana" to serve as the
power enable. Additionally, the HID values SONY471A and TBE20A0, both
associated with the IMX471 image sensor, have been identified on Lenovo
laptops.
