Doug Anderson 870556a3df mmc: dw_mmc: Handle late vmmc regulators with EPROBE_DEFER
It is possible to specify a regulator that should be turned on when
dw_mmc is probed.  At the moment dw_mmc will fail to use the regulator
properly if the regulator probes after dw_mmc.  Fix this problem by
honoring EPROBE_DEFER.

At the same time move the regulator code out of the slot init code.
We only specify one regulator for the whole device and other parts of
the code (like suspend/resume) assume that the regulator has only been
enabled once.
