This patchset adds the MMC controller B and C to the g12a SoC as well
as the u200 and sei510 boards.

MMC controller A has been left out on purpose. This controller is
special on this SoC family and will be added later on.

Notice the use of the pinconf DT property 'drive-strength-microamp'.
Support for this property is not yet merged in meson pinctrl driver but
the DT part as been acked by the DT maintainer [0] so it should be safe
to use.

Add port B (sdcard) and port C (eMMC) pinctrl and controllers nodes to
the g12a DT.

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
