Replace the "arm,cortex-a9-gic" compatible value for the GIC by
"arm,pl390", as the documentation states it is a PL390.
This has been confirmed (thanks Simon!) by reading the GICD_IIDR
register, which reports 0x0000043b (PL390 = 0x00, ARM = 0x43b).

This has no effect on runtime behavior, as currently the GIC driver
treats both compatible values the same.
