arm64: secmon: add entry point for turned on CPUs

Browse Source 
Newly turned on CPUs need a place to go bring its EL3
state inline with expectations. Plumb this path in for
CPUs turning on as well as waking up from a power down
state. Some of the infrastructure declarations were
moved around for easier consumption in ramstage and
secmon. Lastly, a psci_soc_init() is added to
inform the SoC of the CPU's entry point as well do
any initialization.

BUG=chrome-os-partner:32112
BRANCH=None
TEST=Built and booted. On entry point not actually utilized.
