uboot: (firmwareOdroidC2/C4) don't invoke patch tool, use patches = [] instead

https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      Wiggle applies patches to a file in a similar manner to the patch(1)
+      program. The distinctive difference is, however, that wiggle will
+      attempt to apply a patch even if the "before" part of the patch doesn't
+      match the target file perfectly. This is achieved by breaking the file
+      and patch into words and finding the best alignment of words in the file
+      with words in the patch. Once this alignment has been found, any
+      differences (word-wise) in the patch are applied to the file as best as
+      possible. Also, wiggle will (in some cases) detect changes that have
+      already been applied, and will ignore them.
