target/arm/kvm64.c: Remove unused include

The include of hw/arm/virt.h in kvm64.c is unnecessary and also a
layering violation since the generic KVM code shouldn't need to know
anything about board-specifics.  The include line is an accidental
leftover from commit 15613357ba53a4763, where we cleaned up the code
to not depend on virt board internals but forgot to also remove the
now-redundant include line.
