I guess the easiest option would be to just drop the dwc2 from here, only 
keeping the phy enablement and let everything (Marek's and Sjoerd's patch) 
come together in the armsoc defconfig branch? As the rest of both patches don't 
seem to touch common areas, they should be easily mergable from different trees 
as well.
