29fdedfed5 spapr: add vio-bus devices to categories
In order to get devices appear in output of
"./qemu-system-ppc64 -device ?",
they must be assigned to one of DEVICE_CATEGORY_XXXX.

This puts VIO devices classes to corresponding categories.

210b580b10 spapr-rtas: add CPU argument to RTAS calls
RTAS is a hypervisor provided binary blob that a guest loads and
calls into to execute certain functions.  It's similar to the
vsyscall page in Linux or the short lived VMCI paravirt interface
from VMware.

The QEMU implementation of the RTAS blob is simply a passthrough
that proxies all RTAS calls to the hypervisor via an hypercall.

While we pass a CPU argument for hypercall handling in QEMU, we
don't pass it for RTAS calls.  Since some RTAs calls require
making hypercalls (normally RTAS is implemented as guest code) we
have nasty hacks to allow that.

Add a CPU argument to RTAS call handling so we can more easily
invoke hypercalls just as guest code would.

fd506b4f61 pseries: Convert VIO code to QOM style type safe(ish) casts
Curerntly the pseries VIO device code contains quite a few explicit
uses of DO_UPCAST and plain C casts.  This is (obviously) type unsafe,
and not the conventional way of doing things in the QOM model.  This
patch converts the code to use the QOM convention of per-type macros
to do verified casts with OBJECT_CHECK().
