Subdriver for Logitech UltraX keyboard improved.

• Added mapping from usages to HelenOS keycodes - now lists only the Usages used by this keyboard + some other which are result of bad parsing of the report (will be removed, now only for demonstration purposes).
• Added lgtch_init() and lgtch_deinit() functions (also to the subdriver mapping).
• Some code of key handling is copied from boot kbd subdriver.
• The subdriver creates its own DDF function and adds it into the 'keyboard' class, so that the console connects to it.
• Fixed iterating over report.
