Subject: [PATCH] arm64: dts: layerscape: Fix GICv3 ITS node names

The GICv3 ITS is an MSI controller, therefore its node name should be
'msi-controller'.

Note that this exposes an issue that #msi-cells is missing. In turn, the 
use of msi-parent in PCI nodes is wrong and should be msi-map according 
to my sources (Robin M), but I have no idea what is correct there.
