arm64: dts: st: Use 128kB size for aliased GIC400 register access on stm32mp25 SoCs

Browse Source 
[ Upstream commit 06c231fe953a26f4bc9d7a37ba1b9b288a59c7c2 ]

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")
