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.

+      Unified Parallel C (UPC) is an extension of the C programming language
+      designed for high performance computing on large-scale parallel
+      machines.The language provides a uniform programming model for both
+      shared and distributed memory hardware. The programmer is presented with
+      a single shared, partitioned address space, where variables may be
+      directly read and written by any processor, but each variable is
+      physically associated with a single processor. UPC uses a Single Program
+      Multiple Data (SPMD) model of computation in which the amount of
+      parallelism is fixed at program startup time, typically with a single
+      thread of execution per processor.
