Subject: [PATCH 6/6] hw/arm/virt: Check no_tcg_its and minor style changes

RH-Author: Eric Auger <eric.auger@redhat.com>
RH-MergeRequest: 57: hw/arm/virt: Add 9.0 machine type and remove 8.5 one
RH-Commit: [6/6] 4480d569463fd3f637404539d3bd06b59cafbc88 (eauger1/centos-qemu-kvm)
RH-Bugzilla: 2031044
RH-Acked-by: Gavin Shan <gshan@redhat.com>
RH-Acked-by: Andrew Jones <drjones@redhat.com>
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>

branch: c9s
Brew: 42213566
Upstream: no

Truly allow TCG ITS instantiation according to the no_tcg_its
class flag. Otherwise it is always set to false.

We also take benefit of this patch to do some minor non
functional style changes to be closer to the upstream code.
