a52f883b10 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.

135eae91d5 soc/intel/apollolake: Implement stage cache to improve resume time
This patch enables stage cache to save ~40ms during S3 resume.
It saves ramstage in the stage cache and restores it on resume
so that ramstage does not have to reinitialize during the
resume flow. Stage cache functionality is added to postcar stage
since ramstage is called from postcar.

BUG=chrome-os-partner:56941
BRANCH=none
TEST=built for Reef and tested ramstage being cached

TEST=Boot and verify that microcode tries to load into the BSP.

0e55632661 cpu/x86/mp_init: remove unused callback arguments
The BSP and AP callback declarations both had an optional argument
that could be passed. In practice that functionality was never used
so drop it.

9d903a1dd3 soc/apollolake: Enable all CPU cores using the parallel MP lib
This is the minimal setup needed to get all CPU cores enabled. That
includes sending an IPI to APs and setting up MTRRs. Microcode updates
are not performed for two reasons:
* CSE (Converged Security Engine) upgrades the microcode before
  releasing reset
* Microcode update files are not available at this point in time
