openeuler_defconfig: Enable Phytium FT-2500 support by default

hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I41AUQ
CVE: NA

-------------------------------------------------

While compiling with openeuler_defconfig, configs CONFIG_ARCH_PHYTIUM
and CONFIG_ARM_GIC_PHYTIUM_2500 should be set to enable support for
Phytium ARMv8 S2500/FT-2500 SoC and 2-Processor server.

Enable these two configs for arch/arm64/configs/openeuler_defconfig
by default.

Note: As FT-2500 2-Processor server has 16 NUMA nodes, CONFIG_NODES_SHIFT
should be 4.
