The hip04 ethernet driver causes a new compile-time warning
when built as a loadable module:

WARNING: modpost: missing MODULE_LICENSE() in drivers/net/ethernet/hisilicon/hip04_eth.o
see include/linux/module.h for more information

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