Subject: mmc: core: Export a few functions needed for blkmq support
Git-commit: cb39f61e9b1e675c8df86df69d53f08334b34077
Patch-mainline: v4.15-rc1
References: FATE#324519

The following functions are needed by the mmc block device driver, once it
converts to blkmq, therefore let's export them.

mmc_start_bkops()
mmc_start_request()
mmc_retune_hold_now()
mmc_retune_release()
