soc/apollolake: Add soc core init
Skip FSP initiated core/MP init as it is implemented and initiated
in coreboot.
Add soc core init to set up the following feature MSRs:
1. C-states
2. IO/Mwait redirection
BUG=chrome-os-partner:56922
BRANCH=None
TEST= Check C-state functioning using 'powertop'. Check 0xE2 and
0xE4 MSR to verify IO/Mwait redirection.
