staging: android: fwdata: add missing MODULE_LICENSE

The intel fwdata driver causes a new compile-time warning
when built as a loadable module:

WARNING: modpost: missing MODULE_LICENSE() in drivers/staging/android/fwdata.o
see include/linux/module.h for more information

This adds the license as "GPL v2", which matches the header of the file.
