The function mmc_send_cxd_data() sends a data read command of ADTC type and prepares to receive an R1 response. To make it even more re-usable, let's extend it with another in-parameter for the command argument. While at it, let's also rename the function to mmc_send_adtc_data() as it better describes its purpose. Note that, this change doesn't add any new users of the function. Instead that is done from subsequent changes.
