I assume port A is missing due to the controller bug (missing DDR
access) for which Neil has sent a fix. this shouldn't stop us from
adding SD card and eMMC support though
first I was surprised to see that the MMC controllers are not part of any bus.
however, the public S922X datasheet mentions the MMC controllers
directly in the memory map (on page 83), so Jerome is doing the right
thing here as far as I can tell
