mmc: core: Extend re-use of __mmc_poll_for_busy()
Via __mmc_poll_for_busy() we end up polling with the ->card_busy() host ops
or by sending the CMD13. To allow polling of different types, which is
needed to support a few new SD card features, let's rework the code around
__mmc_poll_for_busy() to make it more generic.
More precisely, let __mmc_poll_for_busy() take a pointer to a callback
function as in-parameter, which it calls to poll for busy state completion.
Additionally, let's share __mmc_poll_for_busy() to allow it to be re-used
outside of mmc_ops.c. Subsequent changes will make use of it.
