[U-Boot] [PATCH v3 01/12] input: Support the German keymap

Wed Nov 11 18:05:37 CET 2015
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 at 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
