IBMASM: miscellaneous fixes

IBMASM: miscellaneous fixes

Fix some minor issues, such as:
 - properly set up ID of keyboard device (was mixed up with mouse)
 - constify translation tables
 - change some variables to #defines
 - set up input device's parent to form proper sysfs hierarchy
 - minor formatting changes
