The "u-boot,dm-pre-reloc" thing should of course stay in u-boot specific 
DTs. But I had to add many missing "resets = " references that are yet 
missing in upstream Linux DTs. Dinh is in the process of adding them and 
I'll make sure to sync that back to U-Boot once it's in Linux mainline 
git. I just did not want to wait until that happens...
