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!
