This is definitely wrong. The GICC region cannot be less than
8kB, as the GICC_DIR register is in the second 4kB region.

I'm pretty sure the kernel shouts at you when booting at EL2.
Got it, will update the size to 8kB

+                  <0x0b004000 0x1000>;  /* GICV */

Same thing here.
okay

+            #address-cells = <1>;
+            #size-cells = <1>;
+            interrupt-controller;
+            #interrupt-cells = <3>;
+            interrupts = <GIC_PPI 9 IRQ_TYPE_LEVEL_HIGH>;

Missing target CPU encoding.
Okay, will update the interrupts as below. Hope this is the expectation?
Please let us know if we are missing something
interrupts = <GIC_PPI 9 (GIC_CPU_MASK_SIMPLE(4) | IRQ_TYPE_LEVEL_HIGH)>;
