The GICv3 ITS is an MSI controller, therefore its node name should be
'msi-controller'. The ITS node is also expected to have '#msi-cells'.
Add it on Thunder as there are no users. Thunder2 uses 'msi-parent', but
Robin says that should be 'msi-map' instead and I'm not sure what's
correct for it.
The unit-addresses of both the ITS and main GIC node on thunder2 are also
wrong, so fix them while we're here.
