platform/x86: fujitsu-laptop: make disable_brightness_adjust a boolean
Due to the way the disable_brightness_adjust module parameter is
currently handled in acpi_fujitsu_bl_add(), it can only be set to either
0 or 1, which effectively makes it a boolean. Emphasize that by
changing module parameter type to bool. Do not announce parameter value
in a debug message as it can be dynamically changed via sysfs and its
current value can also be read from there. Clean up module parameter
description.
