Presumably someone might decide not to use the MMC in some case (perhaps
only mounting it when explicitly needed in order to save power for
example, or the MMC subsystem might figure out a way to power down an
idle MMC block device).

That's probably fine, or do it via runtime PM (the framework is fairly
simple to use, I'll probably go add support in the core for it in the
next day or two as this seems like a sensible use case).  I can't
remember if this device is a MFD or not and I'm just on my way out the
door.
