[RFC PATCH 10/10] mmc: improve API to make clear hw_reset callback is for cards

To make it unambiguous that the hw_reset callback is for cards and not
for controllers, we add 'card' to the callback name and convert all
users in one go. We keep the argument as mmc_host, though, because the
callback is used very early when mmc_card is not yet populated.
