The ROHM BU27034NUC was cancelled and BU27034ANUC is replacing this
sensor. These senors aren't compatible from the software point of view.

According to ROHM, the BU27034NUC was never mass-produced. Hence dropping
the BU27034NUC support and using this driver to support BU27034ANUC
should not be a problem to users. We however need to ensure than people
who use old kernel with the old BU27034NUC driver don't get the old
driver probed for the new sensor.

Prepare to use the BU27034NUC driver to support the new BU27034ANUC and
change the compatible to prevent probing the old driver with the new
sensor.
