arm64: dts: socfpga: Add Agilex5 SVC node with memory region

Browse Source 
Introduce the Stratix10 SoC Service Layer (SVC) node for Agilex5 SoCs. This
node includes the compatible string "intel,agilex5-svc" and references a
reserved memory region used for communication with the Secure Device
Manager (SDM).

Agilex5 introduces changes in how reserved memory is mapped and accessed
compared to previous SoC generations. This commit updates the device tree
structure to support Agilex5-specific handling of the SVC interface.
