[PULL 44/46] kvm: move target-dependent interrupt routing out of kvm-all.c

[Paolo Bonzini <pbonzini@redhat.com>]

Let hw/hyperv/hyperv.c and hw/intc/s390_flic.c handle (respectively)
SynIC and adapter routes, removing the code from target-independent
files.  This also removes the only occurrence of AdapterInfo outside
s390 code, so remove that from typedefs.h.
