Revert "sdhci: force high speed capability on some controllers"
This reverts commit a4b76193774b463b922cab2f92450efb20d29ef0. It turned out that the controller had problem running at the higher speed, so go back to trusting the hardware capability bits. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
