Sorry, I must have cherry-picked this commit without the changes I made after v1 review and send it out as v2. It would explain why I still have those typos and there is no reordering. V4 will have it fixed.

> Hello Mateusz,

> For "Reordered the SD_MMC_BUS_MODE to fix problem with driver never
> choosing the DDR50 speed mode", it seems to me that the change is not
> covered by this patch. Did I miss it?
>
> Also, a couple of typos:
> unsuportted -> unsupported
> choosen -> chosen
>
> Others look good to me.
