We've always had that, the BBBlack wouldn't work without it either and
the BBBlack works fine. It's like it needs a different regulator or
something.
Okay, that's weirder then. They both share the same tps65217
regulator. The black has one regulator (ldo3_reg) that's different,
but it should be taken care of in the dts.
