platform/x86: fujitsu-laptop: Clean up constants

Browse Source 
Align all constant values defined in the module to a common indentation.
Rename ACPI_FUJITSU_NOTIFY_CODE1 to ACPI_FUJITSU_NOTIFY_CODE as there is
only one ACPI notification code used throughout the driver.  Define all
bitmasks using the BIT() macro.  Clean up comments.
