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.

+# ibus-engines.typing-booster {#sec-ibus-typing-booster}
+
+This package is an ibus-based completion method to speed up typing.
+
+## Activating the engine {#sec-ibus-typing-booster-activate}
+
+IBus needs to be configured accordingly to activate `typing-booster`. The configuration depends on the desktop manager in use. For detailed instructions, please refer to the [upstream docs](https://mike-fabian.github.io/ibus-typing-booster/documentation.html).
+
+On NixOS, you need to explicitly enable `ibus` with given engines before customizing your desktop to use `typing-booster`. This can be achieved using the `ibus` module:
+
+```nix
+{ pkgs, ... }: {
+  i18n.inputMethod = {
+    enabled = "ibus";
+    ibus.engines = with pkgs.ibus-engines; [ typing-booster ];
+  };
+}
+```
+
+## Using custom hunspell dictionaries {#sec-ibus-typing-booster-customize-hunspell}
+
+The IBus engine is based on `hunspell` to support completion in many languages. By default, the dictionaries `de-de`, `en-us`, `fr-moderne` `es-es`, `it-it`, `sv-se` and `sv-fi` are in use. To add another dictionary, the package can be overridden like this:
+
+```nix
+ibus-engines.typing-booster.override { langs = [ "de-at" "en-gb" ]; }
+```
+
+_Note: each language passed to `langs` must be an attribute name in `pkgs.hunspellDicts`._
+
+## Built-in emoji picker {#sec-ibus-typing-booster-emoji-picker}
+
+The `ibus-engines.typing-booster` package contains a program named `emoji-picker`. To display all emojis correctly, a special font such as `noto-fonts-emoji` is needed:
+
+On NixOS, it can be installed using the following expression:
+
+```nix
+{ pkgs, ... }: { fonts.fonts = with pkgs; [ noto-fonts-emoji ]; }
+```
