[S390] Add config option for z196 code generation.
Add a kernel config option for the IBM zEnterprise 196. This will produce faster code on newer compilers using the -march=z196 option. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
