fujitsu-laptop: Use RFKILL support bitmask from firmware

Up until now, we polled the rfkill status for every incoming FUJ02E3 ACPI event.
It turns out that the firmware has a bitmask which indicates what rfkill-related
state it can report.
The rfkill_supported bitmask is now used to avoid polling for rfkill at all in
the notification handler if there is no support. Also, it is used in the platform
device callbacks. As before we register all callbacks and report "unknown" if the
firmware does not give us status updates for that particular bit.

This was fed through checkpatch.pl and tested on the S6420, S7020 and P8010
platforms.
