A randconfig build showed that two clk modules have no license tag:
WARNING: modpost: missing MODULE_LICENSE() in drivers/clk/keystone/gate.o
see include/linux/module.h for more information
WARNING: modpost: missing MODULE_LICENSE() in drivers/clk/keystone/pll.o
see include/linux/module.h for more information
Add the appropriate information from the comment at the start of the
two files.
