[U-Boot] [PATCH 04/13] mmc: tmio: Configure clock before any other IOS

Configure the clock settings before reconfiguring any other IO settings.
This is required when the clock must be stopped before changing eg. the
pin configuration or any of the other properties of the bus. Running the
clock configuration first allows the MMC core to do just that.
