armv8: layerscape: properly use CPU_RELEASE_ADDR

Browse source 
The generic armv8 code already has support to bring up the secondary
cores. Thus, don't hardcode the jump in the layerscape lowlevel_init to
the spin table code; instead just return early and let the common armv8
code handle the jump. This way we can actually use the CPU_RELEASE_ADDR
feature.
