Now that we have improved the runtime power management powerup/powerdown code, we believe that MMC_CAP_POWER_OFF_CARD is no longer necessary: runtime PM should now work everywhere.
Enable this trivially for a release or two. If no problems are reported, we will follow up with a more extensive patch to remove this flag altogether. If problems are reported, we can look at whitelist/blacklist possibilities as before.
