During boot, Linux kernel complains:

[    0.000000] GIC: GICv2 detected, but range too small and irqchip.gicv2_force_probe not set

This SoC is using a regular GIC-400 and the GICR space size should be
8KB rather than 256B.

With this patch:

[    0.000000] GIC: Using split EOI/Deactivate mode

So this should be the correct fix.
