I was thinking about this for quite a time, and I'm afraid that this patch
solves only one corner case - that some specific actions need to be
taken _after_ mmc regulator is adjusted, while excluding the possibility
for that to happen _before_. I wonder maybe for those corner cases,
if one can just manipulate the vmmc regulator and other specific stuffs
within ->setpower().
