To make it unambiguous that mmc_hw_reset() is for cards and not for
controllers, we make the function argument mmc_card instead of mmc_host.
Also, all users are converted.

Ulf prefers one cross-subsystem patch to have all users converted. So,
we are looking for ACKs from the maintainers of the wireless drivers.
Thank you!
Changes since RFC:
* don't rename the function but only change the argument type
* remove fallback and convert all users in one go
* remove comment as suggested by Ulf
