efi: don't look for chosen@0 node on DT platforms

Due to some scary special case handling noticed in drivers/of, various bits of the ARM* EFI support patches did duplicate looking for @0 variants of various nodes. Unless on an ancient PPC system, these are not in fact required. Most instances have become refactored out along the way, this removes the last one.
