[S390] zcrypt driver Makefile, Kconfig and monolithic build.
The Makefile and Kconfig changes should be obvious. The monolithic build option is there to create an old-style z90crypt module for backward compatability to older distributions. Signed-off-by: Ralph Wuerthner <rwuerthn@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
