arm64: Add support ARCH_SUPPORTS_INT128
The gcc support __SIZEOF_INT128__ and __int128 in arm64, thus, enable ARCH_SUPPORTS_INT128 to make mul_u64_u32_shr() a bit more efficient in scheduler. Signed-off-by: Kefeng Wang <wangkefeng.wang@huawei.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
