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.

A number of users are reporting stalls when using the pseries
hypervisor virtual console.
A simple test case is to paste 15 or 17 characters at a time
into the console. Pasting 15 characters at a time works fine
but pasting 17 characters hangs for a random amount of time.
Other activity (network, qemu monitor etc) unblocks it.
If qemu-char tries to send more than 16 characters at once,
vty_can_receive returns false. At this point we have to
wait for the guest to consume that output. Everything is good
so far.
The problem occurs when the the guest does consume the output.
We need to signal back to the qemu-char layer that we are
ready for more input. Without this we block until something
else kicks us (eg network activity).

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().
