mmc: sdhci: Do not call implementations of mmc host ops directly
Drivers must be able to provide their own implementations for mmc host operations. Consequently, SDHCI should call those not the default implementations. Do that by calling indirectly through the mmc host ops function pointers. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
