mmc: core: Record card drive strength
In preparation for adding drive strength support for eMMC, add drive_strength to struct mmc_card to record the card drive strength for UHS-I modes and HS200 / HS400. For eMMC this will be needed when switching between HS200 and HS400. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
