[PATCH 10/12] arm64: dts: st: Add v2m to GIC node on stm32mp251

[Antonio Borneo]

From: Christian Bruel <christian.bruel at foss.st.com>

The GIC of STM32MP25 includes v2m extension for PCIEe MSI support.

Add the v2m sub-node to the GIC interrupt controller and adapt the
other properties accordingly.
