Add support for the German keymap, taken from i8042.c. This can be selected when the input library it initialised.
Signed-off-by: Simon Glass sjg@chromium.org ---
Changes in v3: - Refactor the German keyboard code to use data rather than code
Changes in v2: - Update input_add_tables() to add error checking
