Commit b5ca117365 ("ima: prevent kexec_load syscall based on runtime
secureboot flag") and commit 268a784049 ("s390/kexec_file: Disable
kexec_load when IPLed secure") disabled the kexec_load syscall based
on the secureboot mode. Commit 9e2b4be377 ("ima: add a new CONFIG
for loading arch-specific policies") needed to detect the secure boot
mode, not to load an IMA architecture specific policy. Since there is
the new CONFIG_INTEGRITY_SECURE_BOOT, drop
CONFIG_IMA_SECURE_AND_OR_TRUSTED_BOOT for s390.
