hulk inclusion
category: Feature
bugzilla: https://bugzilla.openeuler.org/show_bug.cgi?id=52
CVE: NA

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

To enable support for Phytium ARMv8 S2500/FT-2500 SoC
and 2-Processor server, add phytium-2500 specific interrupt
controller driver based on ARM original irq-gic-v3.c
and irq-gic-v3-its.c
