arm64: dts: st: Use 128kB size for aliased GIC400 register access on stm32mp23 SoCs
Adjust the size of 8kB GIC regions to 128kB so that each 4kB is mapped 16
times over a 64kB region.
The offset is then adjusted in the irq-gic driver.
see commit 12e14066f4835 ("irqchip/GIC: Add workaround for aliased GIC400")
