arch: arm64: Add arm64_gic_raise_sgi() for SMP

Browse source 
Summary:
- I noticed that arm64_gic_raise_sgi() is not implemented for
  GICv2 which is used for SMP + hypervisor such as qemu + kvm.
- This commit fixes this issue

Impact:
- None

Testing:
- Tested with qemu-7.1 + kvm (linux) and qemu-7.1 + hvf (macOS)
