mmc: sdhci: Remove the sdhci exported header file
Since there no users of the struct sdhci_host, but the shdci host drivers themselves, let's move the definition of it to the local sdhci header. The exported sdhci header then becomes empty, so let's remove it. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
