[PATCH v2 07/10] irqchip/gic-v5: Use firmware node name in ITS warning

[Sascha Bischoff <sascha.bischoff@arm.com>]

The common ITS initialiser can be called with an ACPI firmware node.
If firmware leaves the ITS enabled, the warning dereferences the DT
node pointer, which is NULL on that path.

Use the firmware node name for the warning and drop the DT-only pointer.
