[PATCH] qemu-kvm: Build fixes for ppc64-softmmu

[Benjamin Herrenschmidt <benh@kernel.crashing.org>]

This is a small collection of build fixes that allow the
qemu-kvm tree to build a ppc64-softmmu target with kvm
enabled (provided device-assignment is disabled).

Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Avi, Marcelo: This is really only for qemu-kvm, not upstream qemu,
but since distros such as Fedora use this as base qemu source tree,
it would be great to have these fixed.
