792 MHz is the default on i.MX6. With more drivers one could change
voltages and clock up the processor to up to 1.2 GHz.

The SoC itself has 3 SD card controllers. How many are exposed on the
board is up to the board designer. In this case the 3rd SD card slot
is probably used internally for the SDIO-connected WiFi chip.
