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.

+    longDescription = ''
+      BearSSL is an implementation of the SSL/TLS protocol (RFC 5246)
+      written in C. It aims at offering the following features:
+
+      * Be correct and secure. In particular, insecure protocol versions and
+        choices of algorithms are not supported, by design; cryptographic
+        algorithm implementations are constant-time by default.
+
+      * Be small, both in RAM and code footprint. For instance, a minimal
+        server implementation may fit in about 20 kilobytes of compiled code
+        and 25 kilobytes of RAM.
+
+      * Be highly portable. BearSSL targets not only “big” operating systems
+        like Linux and Windows, but also small embedded systems and even
+        special contexts like bootstrap code.
+
+      * Be feature-rich and extensible. SSL/TLS has many defined cipher
+        suites and extensions; BearSSL should implement most of them, and
+        allow extra algorithm implementations to be added afterwards,
+        possibly from third parties.
