s390x/kvm: Add function for injecting pgm access exceptions
Program access exceptions are defined to deliver a translation exception
code in the low-core. Add a function trigger_access_exception() that
generates the proper program interrupt on both KVM and non-KVM systems
and switch the existing code to use it.
