When we added Allwinner SoC support to ARMv8, we needed to pull in an implementation of lowlevel_init() calling the C function s_init(), as sunxi required it as this time.
The last few patches got rid of this bogus requirement, and as sunxi was still the only user, we can now remove this lowlevel_init.S from ARMv8 altogether.
