vmmc and vqmmc regulators control the voltage to
the host and device. Defer the probe if either of
them is not registered.

Does this work with boards where we don't have any MMC supplies? Or are
we just deferring the probe indefinitely there?

For boards that power MMC unconditionally, are we supposed to add dummy
regulators to make them work with this patchset?

I believe that dummy (fixed) regulators are supposed to be provided in
all cases where the platform doesn't actually have one. The fact that
everything worked OK without them before this patch was most likely a
mistake/accident.
