Some of the Powkiddy devices switched to using a different vendor for the vdd_cpu regulator. Unfortunately the device does not have a new revision to denote this, so users have no way of knowing in advance. Add code to detect if a device is present at addresses 0x1c or 0x40 on the i2c0 bus and update the devicetree if needed.
