Subject: [PATCH 42/56] ich9: APIs for pc guest info

RH-Author: Michael S. Tsirkin <mst@redhat.com>

O-Subject: [PATCH qemu-kvm RHEL7.0 v2 42/57] ich9: APIs for pc guest info
Bugzilla: 1034876
RH-Acked-by: Igor Mammedov <imammedo@redhat.com>
RH-Acked-by: Marcel Apfelbaum <marcel.a@redhat.com>
RH-Acked-by: Laszlo Ersek <lersek@redhat.com>

This adds APIs that will be used to fill in
acpi tables, implemented using QOM,
to various ich9 components.
Some information is still missing in QOM,
so we fall back on lookups by type instead.
