[PATCH 3/3] wistron_btns: add MODULE_DEVICE_TABLE

["Stefan Lippers-Hollmann" <s.L-H@gmx.de>]

This allows the wistron_btns module to be autoloaded on boot, its functionality
is required to support the hardware rfkill switches on most of the supported
notebooks, in order to unblock the hard blocked rfkill state for wireless and
bluetooth devices.

Tested on a Medion MD96500:

This patch may be considered RFC, while it is certainly the right thing to do,
some of the DMI matches might be a bit wide, e.g.:
dmi*:svn*FUJITSUSIEMENS*:pn*AMILOD*:
dmi*:svn*FUJITSUSIEMENS*:pn*AmiloD*:
dmi*:svn*FUJITSUSIEMENS*:pn*AMILOM*:
all others are very targetted - and I haven't noticed any issues by forcing
wistron_btns on system not requiring it so far.
