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.

+      cc65 is a complete cross development package for 65(C)02 systems,
+      including a powerful macro assembler, a C compiler, linker, librarian and
+      several other tools.
+
+      cc65 has C and runtime library support for many of the old 6502 machines,
+      including the following Commodore machines:
+
+      - VIC20
+      - C16/C116 and Plus/4
+      - C64
+      - C128
+      - CBM 510 (aka P500)
+      - the 600/700 family
+      - newer PET machines (not 2001).
+      - the Apple ][+ and successors.
+      - the Atari 8-bit machines.
+      - the Atari 2600 console.
+      - the Atari 5200 console.
+      - GEOS for the C64, C128 and Apple //e.
+      - the Bit Corporation Gamate console.
+      - the NEC PC-Engine (aka TurboGrafx-16) console.
+      - the Nintendo Entertainment System (NES) console.
+      - the Watara Supervision console.
+      - the VTech Creativision console.
+      - the Oric Atmos.
+      - the Oric Telestrat.
+      - the Lynx console.
+      - the Ohio Scientific Challenger 1P.
+
+      The libraries are fairly portable, so creating a version for other 6502s
+      shouldn't be too much work.
