s390: add a few more SPDX identifiers 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 <schwidefsky@de.ibm.com>

s390/crypto: Provide s390 specific arch random functionality. This patch introduces s390 specific arch random functionality. There exists a generic kernel API for arch specific random number implementation (see include/linux/random.h). Here comes the header file and a very small static code part implementing the arch_random_* API based on the TRNG subfunction coming with the reworked PRNG instruction. The arch random implementation hooks into the kernel initialization and checks for availability of the TRNG function. In accordance to the arch random API all functions return false if the TRNG is not available. Otherwise the new high quality entropy source provides fresh random on each invocation. The s390 arch random feature build is controlled via CONFIG_ARCH_RANDOM. This config option located in arch/s390/Kconfig is enabled by default and appears as entry "s390 architectural random number generation API" in the submenu "Processor type and features" for s390 builds.
