samples/boards/nrf/battery does not build

[SebastianBoe]

The sample samples/boards/nrf/battery does not build for platform nrf52_pca20020 on the latest master.

That platform is in the sample.yaml's whitelist, so it should be supported.

Perhaps there has been some backwards-incompatible change to DT voltage.
