Indeed, mmc modules are not loaded. But loading them manually does not
help to get mmc device to appear. I think we are missing other drivers
(maybe GPIO).

Adding TWL4030 gpio as built-in instead of module does help to boot on MMC.
What would be the best way to add this patch? I would say:
* Adding kernel-default (and kernel-source?) to 13.1:Ports to fix current
version
* Adding it to 13.1/master GIT repo for futur versions
