I'm not adding another regulator, but instead simply exposing the fact
(or rather my guess) that the same regulator (vmmc1) is powering the
two MMC channels. Not having access to the board schematics, I can't
tell if that reflects the reality or not.

But using CONFIG_DUMMY_REGULATOR seems the wrong idea to me, as it's
just papering over the issue. We should be exposing what's really on
the board (a fixed regulator if that's the case).
