commit f5f9c6ea11bc807664fdeb9354915c2c9cdcbd89

hw/s390x: Move KVM specific PV from hw/ to target/s390x/kvm/
Protected Virtualization (PV) is not a real hardware device:
it is a feature of the firmware on s390x that is exposed to
userspace via the KVM interface.
Move the pv.c/pv.h files to target/s390x/kvm/ to make this clearer.

target/s390x/kvm/pv: Provide some more useful information if decryption fails
It's a common scenario to copy guest images from one host to another
to run the guest on the other machine. This (of course) does not work
with "secure execution" guests since they are encrypted with one certain
host key. However, if you still (accidentally) do it, you only get a
very user-unfriendly error message that looks like this:
qemu-system-s390x: KVM PV command 2 (KVM_PV_SET_SEC_PARMS) failed:
header rc 108 rrc 5 IOCTL rc: -22
Let's provide at least a somewhat nicer hint to the users so that they
are able to figure out what might have gone wrong.
