[PATCH] s390: cleanup Kconfig

Sanitize some s390 Kconfig options.  We have ARCH_S390, ARCH_S390X,
ARCH_S390_31, 64BIT, S390_SUPPORT and COMPAT.  Replace these 6 options by
S390, 64BIT and COMPAT.

           Select this option if you want to enable your system kernel to
           handle system-calls from ELF binaries for 31 bit ESA.  This option
           (and some other stuff like libraries and such) is needed for
           executing 31 bit applications.  It is safe to say "Y".
