I'm afraid I have to reject this patch. We need to find a better
solution to the two problems:

1) We want to change cards and still have mmc commands work
2) We don't want eMMC devices to be slowed down by constantly
re-initializing their cards.

Normally, I would err on the side of #1, but there's a simple
workaround. If you replace the card, execute "mmc rescan", and the
card will be reinitialized. Please let me know if that workaround
doesn't work. I hope, in the future, we'll have some code which makes
both possible, by being able to detect that a card has been changed,
but for now I think the current system is reasonably satisfactory to
both cases #1 and #2.
