While still 3.3V, the power of the mmc1 if supplied by an other
regulator.
I do not have schematics for the OPi 2, on the OPi plus schematic the
2 share a regulator. But even if it is another fixed 3.3V regulator,
there is little use in modelling it as a separate regulator when we
cannot control it.
