s390: add a few more SPDX identifiers

2017-12-05T06:51:09Z

Add the correct SPDX license to a few more files under arch/s390 and drivers/s390 which have been missed to far. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. Signed-off-by: Martin Schwidefsky

Hence, they are required for proper DWARF unwinding. Signed-off-by: Hendrik Brueckner Reviewed-and-tested-by: Thomas Richter Signed-off-by: Martin Schwidefsky
