platform/x86: fujitsu-laptop: Fix radio LED detection
Radio LED detection method implemented in commit 4f62568c1fcf
("fujitsu-laptop: Support radio LED") turned out to be incorrect as it
causes a radio LED to be erroneously detected on a Fujitsu Lifebook E751
which has a slide switch (and thus no radio LED). Use bit 17 of
flags_supported (the value returned by method S000 of ACPI device
FUJ02E3) to determine whether a radio LED is present as it seems to be a
more reliable indicator, based on comparing DSDT tables of four Fujitsu
Lifebook models (E744, E751, S7110, S8420).
