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.

+      This VA-API video driver backend provides a bridge to the GEN GPUs through
+      the packaging of buffers and commands to be sent to the i915 driver for
+      exercising both hardware and shader functionality for video decode,
+      encode, and processing.
+      VA-API is an open-source library and API specification, which provides
+      access to graphics hardware acceleration capabilities for video
+      processing. It consists of a main library and driver-specific acceleration
+      backends for each supported hardware vendor.
