mmc: core: Convert mmc_driver to device_driver
The struct mmc_driver adds an extra layer on top of the struct device_driver. That would be fine, if there were a good reason, but that's not the case. Let's simplify code by converting to the common struct device_driver instead and thus also removing superfluous overhead. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
