From: Ulf Hansson <ulf.hansson@linaro.org>

The mmc_power_restore|save_host API is only used by SDIO func drivers. SDIO
func drivers are also moving towards use of runtime pm to accomplish the
the same operation and since this API is not used for mmc and sd it makes
sense to remove the corresponding bus_ops.

Moreover, at least for eMMC the mmc bus_ops is broken, since no consideration
is taken for mmc sleep and mmc power off notify.
