mmc: sdio: fix clock rate setting for SDR12/SDR25 mode
In current code logic, when work in SDR12/SDR25 mode, the final clock rate is incorrect, just the legancy 400KHz, because the card->sw_caps.sd3_bus_mode do not has the flag SD_MODE_UHS_SDR12 or SD_MODE_UHS_SDR25. Besides, SDIO_SPEED_SDR12 is actually value 0, and every mode need to config the timing and clock rate, so remove the ‘if’ operator.
