[PATCH 4/5] armv8: remove no longer needed lowlevel_init.S

[Andre Przywara <andre.przywara@arm.com>]

When we added Allwinner SoC support to ARMv8, we needed to pull in an
implementation of lowlevel_init, as sunxi required it at this time.

The last few patches got rid of this bogus requirement, and as sunxi was
still the only user, we can now remove lowlevel_init from ARMv8
altogether.
