arm64: remove soc_secondary_cpu_init()

The original purpose of soc_secondary_cpu_init() was to provide
a way for the SoC to run code on the secondary processors as
they come up. Now that devicetree based bringup is supported
there's no need to have this functionality.

BUG=chrome-os-partner:31761
BRANCH=None
