Merge Pull Request from: @liyuting 
 
GIC support for Phytium S2500

Kernel-issue：
https://gitee.com/open_euler/dashboard?issue_id=I8UDQQ

Phytium S2500 adjusts the GIC's implementation to support multi-socket system designs.
This patch adds the driver for this new implementation.

Test：
Complete dual-socket server boot test, patch's function is successfully verified. 

Default config change:
< CONFIG_ARCH_PHYTIUM=y
< CONFIG_ARM_GIC_PHYTIUM_2500=y
< CONFIG_NODES_SHIFT=8
< CONFIG_IOMMU_DEFAULT_PASSTHROUGH=y
< CONFIG_ARM64_PA_BITS_48
< CONFIG_HOTPLUG_CPU
< CONFIG_NUMA=y
< CONFIG_ACPI_NUMA=y
< CONFIG_NUMA_BALANCING=y
