This battery appears only to be used by a single board (DA850), so it
makes sense to add this to the Kconfig file so that users don't build
the module unnecessarily. It currently seems to be built for the x86
Arch Linux kernel where it's probably not doing much good.

It would probably also make sense to add "default n" since it only
applies to one board in the entire arch.

BATTERY_LEGO_EV3 is already explicitly set to "m" in the appropriate
defconfig file, so I don't think it would break anything.
