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.
