The main function used to send the command to the card inserted into the SD host slot.
It will assemble the arguments to set the command register and wait for the command

the ResponseData.
@param This A pointer to the EFI_SD_HOST_IO_PROTOCOL instance.
@param CommandIndex The command index to set the command index field of command register.
@param Argument Command argument to set the argument field of command register.
@param DataType TRANSFER_TYPE, indicates no data, data in or data out.
@param Buffer Contains the data read from / write to the device.
@param BufferSize The size of the buffer.
@param ResponseType RESPONSE_TYPE.
@param TimeOut Time out value in 1 ms unit.
@param ResponseData Depending on the ResponseType, such as CSD or card status.
