arm64: dts: st: Use 128kB size for aliased GIC400 register access on stm32mp23 SoCs

Browse Source 
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 12e14066f4 ("irqchip/GIC: Add workaround for aliased GIC400")
