Thanks, Mike !

This paves the road for MMC_CAP_POWER_OFF_CARD.

SDIO core will enable runtime PM for the card only if that cap is set.
As a result, the card will be powered down after boot, and will only
be powered up again when a driver is loaded (and then it's up to the
driver whether power will be kept or not).
