s390/Kconfig: add missing ZCRYPT dependency to VFIO_AP
The VFIO_AP uses ap_driver_register() (and deregister) functions implemented in ap_bus.c (compiled into ap.o). However the ap.o will be built only if CONFIG_ZCRYPT is selected. This was not visible before commit e93a1695d7fb ("iommu: Enable compile testing for some of drivers") because the CONFIG_VFIO_AP depends on CONFIG_S390_AP_IOMMU which depends on the missing CONFIG_ZCRYPT. After adding COMPILE_TEST, it is possible to select a configuration with VFIO_AP and S390_AP_IOMMU but without the ZCRYPT. Add proper dependency to the VFIO_AP to fix build errors: ERROR: modpost: "ap_driver_register" [drivers/s390/crypto/vfio_ap.ko] undefined! ERROR: modpost: "ap_driver_unregister" [drivers/s390/crypto/vfio_ap.ko] undefined!
